I'm an Embedded Software Dev accustom to C to the extent that I managed to trip myself up on a couple of Java coding interviews. I remember hearing about Rust a couple of years back from someone, but they weren't the best spokesman and quite aggressively annoying about it. I ended up avoiding it out of spite and because I didn't think that any language could be as performant as C (or C++, but I don't wanna talk about that language). Your videos are excellent, concise, and extremely convincing. Your WASM sub-series even has me interested in attempting to use egui for a Native/Web app. If I can ever get my hands on a microcontroller, I'm probably at the point where I can say that I'd be willing to give Embedded Rust a try over Embedded C.

@@elliotwilliams7523 If you want some more convincing: At work we have a backend written in PHP with the Laravel framework with a basic nginx and postgres stack. With that, most of our more basic endpoints take somewhere about 50ms per request and despite running multiple processes of PHP for concurrency and PHP 8's new JIT, the whole thing refuses to run past a few hundred requests per second, even with enabling keepalive in the benchmark tool, and just nginx+PHP already consume about 500MB of memory while *idle*. Since I wanted to test out some Rust web frameworks anyways, I decided to rewrite a little part of our API in one of them as a PoC. After a few short experiments I eventually settled on Axum, with SeaORM for the database access. The whole rewrite was a breeze, probably most of it was just translating the database migrations, after that SeaORM just generates the models for you and all that's left is copying a starter from the axum examples and writing the logic for the middlewares and handlers. Since I was only using some of the simple endpoints that was barely any work at all. Once rust-analyzer stopped complaining, the whole thing compiled and worked flawlessly. And the performance is a different order of magnitude entirely. With keepalive, most requests complete in just 0.01ms with about 13000 req/sec, and even without keepalive its about 0.015ms at 8100 req/sec, and the variance of those numbers is also a lot smaller than for PHP. To top it off, the Rust version peaked at just ~43MB of memory under *full load*.

[@aaronwinter7911]

Upfront: I love rust! However, I am not sure about the "rapid iteration cycles". While rust code executes very fast, the rust compiler is fairly slow. Meaning you will wait on the compiler a lot. I suppose it heavily depends on the project you are working on, and how many other steps you have to go through, like unit tests and such.

[@theroboman727]

yeah I agree that its not really about rapid iteration cycles, its more about _less_ iteration cycles, because of the confidence in your code that rust gives you through all the robustness oriented design decisions

[@NoBoilerplate]

Here's the thing, after the first slow compile, all subsequent compiles only compile what is changed. When developing, I typically see re-compiles under 100ms. The trick is to correctly split up your project into sensible modules that the rust compiler can cache the compilation artefacts, as I understand it. I've had recent success in cutting down the INITIAL compile by using github.com/mozilla/sccache which aggressively caches build artifacts, even when clean builds are required (like in rust-analyzer) It's a two-line config: twitter.com/0atman/status/1590118756226805762

@@NoBoilerplate But is that relevant in a CI/CD chain? I'm not sure it can easily take advantage of incremental compilation when there are multiple branches to test in parallel.

[@NoBoilerplate]

@@phenanrithe Rust CI/CD pipelines (along with many compiled languages) must be built differently to dynamically-typed languages. A package cache is ESSENTIAL to your sanity, otherwise, as you say, constant recompilation will be SO SLOW. sccache set up in CI would be LOVELY (and trivial). Our infrastructure (gh actions etc) is set up for dynamic languages by default, which is a reasonable default given what we build today. But all that is needed it to set up a few persistent cache folders or docker volumes and you're off! If you're recompiling the whole dependency tree for any action other than the first one, there's optimisation to be done - it's almost never needed.

[@phenanrithe]

@@NoBoilerplate That's interesting, thanks for the feedback! I've had this issue in other build contexts (HDL compilers for digital chips) which are even more demanding and offer the same incremental build capability, but we decided not to hack our pipeline to support that because it was too risky. I didn't know it was a known issue (or flow) in compiled languages but it makes sense for large projects. We also decided not to use it because sometimes it used to produce faulty results with the tools in the first place, but that's another story. 😅At least I've never had this problem with Rust, thanks to the awesome work they've done with the compiler.

My biggest issue is that it's difficult. People say C is difficult but once you understand the concepts of pointers it's not much more difficult than any other language, rust has a lot of syntax that can be really unorthodox which makes it more difficult to write

[@NoBoilerplate]

Rust is extremely different isn't it! No inheritance, new syntax for lifetime annotations and borrows, and the compiler hates a lot of the standard normal patterns we've been using for decades. I know how you feel. Back in 2020 I crashed out of learning Rust twice. First time due to multiple string types (Haskell's biggest mistake made again, I thought to myself) and second due to lifetime syntax. At the time I had a great mentor who picked me up and helped me back on the path. Most people don't have this. This is why I made my Rust series. Yes Rust is very different from what you're used to. But that's the point. Two features you can't get in C that I think you'll like are (proper!) Macros and the Unsafe system. Macros are nothing like templates or cmptime (they're more like lisp macros), and the unsafe system is a genius way to ring-fence pointer arithmetic, to allow us to build safe abstractions around unsafe pointer code. I did a video on both of them here, and I'd love your opinion on it: kzbin.info/www/bejne/hqawiYqZZd2lgZI Cheers!

[@friend7120]

The mention of "perfect code" always puts me off. In university we had a secure programming module, we read case studies on programming errors that cost lives, and a key theme among them all wasn't choice of language or style, it was the assumptions the engineers made about the quality of their code. I recommend reading the report. It's called "Case Studies of Most Common and Severe Types of Software System Failure", from the International Journal of Advanced Research in Computer Science and Software Engineering. The perfect code thing was also seen a lot years back in the Haskell sphere, which lead to Haskell code being of significantly less quality than was expected, largely because of the assumptions programmers held about the language.

[@NoBoilerplate]

I sympathise with this thinking, I also studied formal system at university, and have tried for over a decade to find a programming language and ecosystem to let me write GOOD ENOUGH code that had loads of safeguards built-in to the language. I also thought it was Haskell, but what turned me off wasn't the community attitude, but I do know what you're talking about there, but Haskell's popularity, or lack, thereof. I need a language that has safety built-in, in a comprehensible way that doesn't scare off normal developers. My first video in this series is called Your Code Can Be Perfect (kzbin.info/www/bejne/h2Skma1-pp2indU) and I want to be clear: I don't think Rust is perfect, but I think it's the best language to write perfect code USING, because of the tools it gives you.

How do you take a mind that thinks in terms of for-loops and pointers to structs describing HW registers and retrain it to think in terms of iterators, closures, and very strict typing? How do you take a blob of bytes received from a serial link whose layout you know and interpret it without resorting to 'unsafe', or to picking it apart byte by byte?

after using Rust for a while, i’m very impressed by a lot of its features. even just the specificity and clarity of the number types compared to the other languages i’ve used (Javascript, Python, and C a little) is really nice. another small detail i like is that a lot of math things like min and max are methods, which was weird at first but then i realized that it results in a method chaining way of doing multiple of those operations which is far more readable than nested function calls

Rust even let’s you have low-cost dynamic typing using traits and boxes, and automates significant amounts of work with the macro system. I have it set up in a personal project to automatically generate a TypeScript API for the frontend by analyzing all of my exported types using macros, which is huge. Whenever I change an API, I just re-run the generator, which enables typescript codegen on all my data types and collects them using linkme before writing a ts file, triggering errors in my frontend anywhere I made a breaking change. I even have an event broker like JS written in rust that avoids copying using Arc and deref proxies that cast the data back into its original type without any safety issues. The fact that I can do that with only a few months of work, completely ironed out and working perfectly, while still maintaining runtime speed of 11x what I need for a real-time application is incredible, and only possible because of Rust

I haven't used it since and I probably don't have much reason to use it anytime soon but I absolutely agree with those people saying it's their favourite language and I still keep it in high regard to this day.

[@NoBoilerplate]

Great that you tried it out, that's how I dipped my toe in, while still doing python day-to-day back in 2020. Why not combine forces! github.com/PyO3/pyo3

I've started to learn Rust and noticed that it has a direct access to the array element, which may produce panic errors. Seems like rust is not so safe as was promised

[@NoBoilerplate]

I too was disappointed about this at first. It's the same with airthmatic - rust does not default to checked math - so divide by zero errors panic at runtime. However, I've started to understand Rust's comprimises - the language MUST have both fast AND safe methods, such as the checked_math module in the standard library, which has safe methods that return `Result`s. Vecs for example have .get doc.rust-lang.org/std/vec/struct.Vec.html#method.get

If Rust is so great, how come there isn't a GUI library for it? When D was only a couple years old, someone ported Eclipse's SWT to it, while the standard library was realistically only about 10% complete and it was a relatively neat and fully functioning port. It's kind of one of the first things anyone spins up if you have any hope targeting desktop, even just duct taping Qt and GTK in there. I can see a bunch of projects started and abandoned or left very incomplete and talk of how this or that approach proved unsatisfactory due to lack of OOP. One of the bigger Rust projects uses a Vue JS frontend for GUI. You say you don't need two languages with Rust, well uh there's a counterexample. I'm probably also going to duct tape some dynamic language and an associated GUI library to the Rust core for my project, plus have several of the GUI bits implemented in C++, which is specifically the language I was hoping not to have to come back to.

[@NoBoilerplate]

I have great news for you, there are both QT and GTK bindings: - www.gtk.org/docs/language-bindings/rust/ - wiki.qt.io/Language_Bindings#Qt_for_Rust_.28Rust-Qt.29 gtk-rs.org looks especially mature, which I am delighted to see! I can highly recommend www.egui.rs as a very full-featured Rust gui library that works natively or in-browser using wasm. If I were to start a GUI app today, I'd use this, specifically with the crates.io/crates/eframe framework. Good luck!

[@SianaGearz]

@@NoBoilerplate Hardly news, i saw most of these. Nobody uses the Qt bindings so who knows what the quality of them is. GTK is seeing a good bit of use in Rust, but then, that's... GTK. It has no screen reader support on Windows or Mac so you can barely even count it as a fully featured toolkit, like sure they have all the really difficult stuff worked out, but 98% of the users aren't on Linux so the feature basically isn't accessible to them. The apps using GTK are more in the... not quite toy but not super complex category, but then that's GTK so it should be fairly difficult to mess up and not too difficult to fix the binding, so i wouldn't have qualms using the binding per se. I'm looking to rewrite an ancient inherited legacy project in Rust which has like 400 dialogues and where lack of accessibility is one of major existing criticisms - it's using a custom retained mode OpenGL based toolkit. Another is lack of multimonitor support via breaking out things in the app into separate windows. I need to retain a good bit of existing feel if not quite the look, avoid too drastic functional changes. Another problem is that the GUI isn't asynchronous at all, and if the rendering of the 3D scene stalls, and it does and it probably will even after the rewrite, so does the UI, so that's something i'm looking to avoid. It also turns out that the layouts of the dialogs are a fairly good match for Qt in particular, i could even automate most of the conversion. There's also some UX... near atrocities that i'm sure people want kept, such as a treebox which reaches tens thousands of entries, so there are performance requirements at play, but only a very very small selection of UI pieces are anywhere near performance sensitive. And the reason that i'm looking to rewrite it is that the application has become slow and fragile, and the more hands touched it, the more fragile it got over the course of over 2 decades. It's over a megaloc of C++, but i feel it could easily be 1/8th of that if it wasn't just layers of bad design. I've also found that rend3 is an exceptionally good fit for my requirements. I've been thinking of also Qt's QML/Quick so i can move a lot of UI code to JS and not have to recompile so much and enable more third party extensibility, but i'm not fully convinced yet in multiple regards. Among these Qt company doesn't seem to take QML accessibility seriously, there is screen reader support but the focus control isn't nearly robust enough to make it work properly, and i don't need a lot of its selling points, i don't need the UI to be fluidly animated etc. I'm also not at all married to JS as a scripting language i'd like to embed, indeed it's kind of a third rate choice, but also i don't have a really strong opinion on what it should be. Egui is bar none the MOST impressive immediate mode toolkit i've ever seen and i'm certainly going to do some quick and dirty prototypes with that, it somehow slipped me by this far. I also love that accessibility is at least somewhat implemented, like it can screenread, but there isn't full keyboard control for floaty windows and their size, which, OK, i can get that fixed up. Also a lot of stuff in the app that i'm to rewrite seems like a poor fit to an immediate-mode toolkit. I don't personally have a first- or even second-hand need for accessibility features, but talking to users, one finds that there's thousands of people who need these sorts of features and are increasingly struggling with modern software. Back in the day, even when i got started 25 years ago in Delphi, accessibility support was basically a given, basically everything was screen readable and keyboard-navigable. Today even such a basic application as Discord, while it can be screen-read (somewhat), it just doesn't have basically any keyboard control at all. We have suffered a massive regression especially since touch-based and web UIs started leaking onto the desktop.

Awesome videos. Great inspiration to learn Rust. I've been trying to figure out how to deal with dependencies of dependencies. Let's say my project depends on crate A which depends on B. A uses some of B's types in its interface without re-exporting them or B. Now what? From what I can gather there is no way to tell cargo that my project also need that specific version of B. Am I missing something?

[@NoBoilerplate]

Unlike in other many other languages crates dependencies are independent. A -> B -> Cv1 and A -> Cv2 (where '->' means 'depends on') Is perfectly legal - just specify the version you want in your cargo.toml Any more questions, come ask in #newbie-advice on my discord!

Rust is great, but it still has to stabilize more on the framework side, especially those targeting the browser. The backend is already well covered. On the frontend the future is promising, but currently I wouldn't write a complex webapp in Rust, the current frameworks are not on the same maturity level as React or Vue. Of course, if you write something with WebGL or Canvas ignoring the DOM, it might already be a perfect choice. But it's not just the problem of tooling, some standardization on the browser level needs to happen so Webassembly can access the DOM without going through JavaScript. But we will get there for sure.

[@trejkaz]

We're at the point where, if I had to write a native launcher, I would do it in Rust. If I had to write native glue code to something native, I would use FFI from whatever language the main code is in, because that is more maintainable than dragging along a hand-written native shim, even if that shim were written in Rust. But actually replacing the Java application with Rust? Not likely. But if we wanted to, here are the main gates in the way: - Rust's UI libraries are still very rudimentary. Even compared to Elixir, and Elixir is already something we want to use in production, but can't, because _its_ UI library isn't ready. - Java has a ton of libraries and sometimes it feels like we're using almost all of them - The quantity of the code that someone would have to migrate somehow

[@NoBoilerplate]

I see what you're saying, but take a step back: Coders in the top 10 languages all say "You can't replace [my language] with Rust, there's too many essential libraries that I use all the time from [my language's community]". I've had people say something like what you said in a dozen languages, including languages (like elixir) that are less popular than Rust and have fewer packages. (Rust: 110,655 packages Elixir: 14,255 packages) Perhaps you're not as familiar with the Rust ecosystem as you are with Java, or perhaps even Elixir? Regarding your specific use case, HTML is the standard interface, and with a project like tauri.app making it first-class on desktop and mobile, I don't see the problem. If your users want NATIVE native, then www.egui.rs is incredible.

[@trejkaz]

@@NoBoilerplate I don't want to use web technologies to make a desktop application, so Tauri is already not an option. (Their web site is also terrible. I had to visit several pages even to figure out that it was just embedding a web browser. Initially I was reading "you can use whatever frontend framework you want", and thinking, "no, I'm looking for a frontend framework, you absolute buffoons.") Egui I have discovered before. I'm not so fond of immediate mode UI because when someone comes by to automate testing for it, they usually complain that there is no way to walk the component hierarchy to find a button to click on. I've also played with their example for long enough to realise that foreign languages don't work in their text renderer and that their emoji rendering is terrible. I'm also aware of Iced, but I haven't looked too closely at that one yet, so I'm not sure. I have read its examples - it is *WAY* more clunky than Jetpack Compose. I'm sure this is because these frameworks are "first attempt" frameworks - they don't have any other Rust frameworks to compete against, so they think they can get away with a somewhat ugly API. But then I come in, comparing with Jetpack Compose, and they look bad. So to answer your question, no, I'm not as familiar with Rust. → The reason I'm not as familiar with Rust is, I haven't used it for 1,000 hours at work. → The reason I haven't used it for 1,000 hours at work is, we haven't found a way to adopt it yet. → And the reason why we haven't found a way to adopt it yet is that we are still yet to find a good UI framework. We're also not confident enough to create that UI framework ourselves - so "just make it yourself" isn't really an option either. Just in case you try to argue that angle. I do acknowledge that 100% of today's code could be rewritten in Rust. It assumes that you're also happy to reimplement all the missing frameworks before you start on the actual code - but the claim is true, with this caveat.

[@just_smilez]

Alright, I'm convinced, it might be worth picking up rust after years of standing by cpp. A few questions to get a handle on how many of my personal projects I might want to consider writing in rust, since you seem to focus mainly on web dev, which is decidedly not what I do. If none of these exist for rust, that's fine; it just means I'll have to figure out other projects to work with in the language: Where should I start looking for libraries to handle hpc - can you write sycl code in rust? I'd prefer to avoid opencl due to poor vendor support. Cuda and hip bindings would be less desirable due to the extra work involved in supporting both, but they'd be useful as well. Please tell me there's more than just an under development spirv wrapper and packages to handle regular shader pipelines; I'm looking to do compute on the gpu, not just shaders. How well does it handle avx and simd? Can the compiler auto vectorize, or are you able to write it by hand? Are the vulkan bindings good? Are there any that actually have first party support?

The standard library is a bit of an outlier in this regard. It's the only place where this shortening is commonplace, and even then, it only occurs for items that are so ubiquitous you'll have them memorized before you finish your first project. For actual libraries full names are the norm. The short names for common std items and lang items do actually make sense. They do reduce character noise.

Rust crate developers are super cautious about releasing 1.0, because that comes with stabilizing the API and disallowing any breaking changes (without major version change, ie. 2.0). What you will find is that many crates are not "stable" (as in 1.0), but they are "mature" (0.x, production ready, with breaking changes being minimized).

I started to learn Rust 2 months ago. Very steep learning curve but it is designed for speed and complex code.

The tools are still in its infancy similar like C# 1.0 without Resharper and the ability of break points. But with the energy crisis, every watt counts. More bare metal power with less energy means cheaper. However not every developer will survive the transition to learning Rust. The ability to adapt and "unlearn" is vital to the transition.

You speak of superior development ergonomics, and for the most part I agree with what is said, though the speed of Rust's compiler itself is concerningly slow. The Linux kernel already takes a very long time to compile. What if it was all Rust? Do you think the compile time issue will be resolved in the future?

[@NoBoilerplate]

There's two sides to this, one side is that people a misremembering that Rust compile times USED to be extremely slow, and articles from before 2020 might confuse you with this conclusion. The Rust compiler has had enormous optimisations since then, and is now much much faster. The Second side is that Rust compile times are indeed slower than go or C++ because the compiler does so much more for us. But it is possible to get around this problem with careful module design. The compiler is very smart about caching, and while an initial compile might take the same time, it is possible to speed up recompilation with good techniques.

@@NoBoilerplate My issues stem from the reliance on llvm only. Which I get, llvm is much simpler to work with than the alternatives, but it’s worrying to put all your eggs in one basket. My other worry is that now, going forward, LLVM being required now by much more code puts the responsibility of keeping older and even newer architectures that will come out solely on LLVM to support. Meaning that future revisions of gentoo and the like won’t support even something simple like ia64, hpaa, s390, among others. So when I see the massive support for Rust, why haven’t I seen a lot of support for bringing in and expanding llvm support before trying to bring it into the linux kernel? Since rust leans so heavily on llvm, this would be an awesome opportunity to see more arch support for llvm which would benefit many and reduce friction. You said it yourself, Rust is a mature language that has been around for well over a decade, so then I ask, why isn’t it seeing the arch support that it should.. if the aim is to bring in and replace C components then it should be better in every way or at least meet the standard. Less than optimal arch support will limit reusability and as a result, keep older but critical systems from receiving the proper support, opening up vulnerabilities for businesses and infrastructure.

[@NoBoilerplate]

@@sleaf6 I'm unfamiliar with the low-level discussion, could you give examples of architectures that LLVM doesn't support?

[@NoBoilerplate]

It's possible that the LLVM's team are RIGHT to not support every architecture, reading this blog.yossarian.net/2021/02/28/Weird-architectures-werent-supported-to-begin-with

My pleasure! Thank you for commenting.

I certainly am impressed with rust after watching your videos. Currently i'm torn between focusing on rust and nim. I believe you dabbled in nim language before, could you share your opinion / what made you settle on rust? Rust seems for me to be more complicated, polished and suitable for big, complex projects. In nim beauty lies in the simplicity and ergonomics of language. Is the rust compiler's safety a killer enough feature for you, or was there something else?

[@NoBoilerplate]

Simplicity is a double-edged sword. No harming in learning how to program on simple languages, but simple syntax harms you. I explain my thinking on the matter in this video kzbin.info/www/bejne/apXZl2mhgpxjp68.

[@NoBoilerplate]

Thank you!

[@explodatedfaces]

To be clear; Rust is the most loved programming language as voted on by 6625 people with 879 of those saying they dread working with it. It had the highest percentage, but one of the lowest number of voters. This is called selection bias... especially considering the total population of people who voted on it in 2022 was only 9.27% of the voters. Any reasonable person would have excluded it from the results as biased for selection and non-response. The most loved language from that survey with substantial enough voters to consider in the final results is TypeScript with 24,752 voters (34.63% of the sampled population).

[@cerulity32k]

Rust is the only language that makes me feel like I can accomplish something *solid.* When writing things in C#, there are exceptions that can just _happen_ and cause the program to come crashing down. Handling exceptions is not very easy either. (While Rust does have the panic!() macro which can be put anywhere, every single competent crate or method I've come across always uses Results, which are inherently explicit and much easier to handle.) I would MUCH prefer: `function().unwrap_or()` than: `try { v = function(); } catch (Exception e) { v = ; }` Not to mention the ? operator. All of Rust's types and mechanisms are not built into the language. Results, Options, Iterators, Deref, Index, Mul, Add, I could go on and on, are simply traits and enums that _you could make yourself._ While special traits like Deref/Index are syntactically special, it's all syntactic sugar which you can take hold of. This means that they can have a ton of helpful functions like map, filter, fold, chunks, enumerate, and unwrap_or. Rust is boring in the sense everything is made the same way and nothing is special, but that makes creating fun stuff much easier.

[@whamer100]

rust is such a cool language, i just get annoyed trying to actually write anything with it. i feel like i have to write a ton more code to do things, and i always feel like im doing it wrong (even if the code actually works)

[@NoBoilerplate]

I know what you mean, it's tough to get going, but I hope in my Rust series that I can show folks that it's worth it! It doesn't seem that way at the start, I agree. The way I think about it is: In other language simple things are easy and hard things are possible, in Rust simple things are possible and hard things are easy. I know which way round I'd prefer to build large programs!

Friend, I have great news. I recently tried out crates.io/crates/vst and the demo vst compiled and loaded into my daw (reaper) perfectly! I'd love to know how you go with this - I want to build my own VSTs too. Join my discord and tell me please! noboilerplate.org/discord

[@KohuGaly]

Yes, it is possible. Unfortunately VST3 API is so C++ infested, that it doesn't really mesh with Rust in ergonomic way. VST2 works quite fine though. Implementing GUI has also proven to be rather challenging, because you're receiving windows from the DAW instead of the OS/Browser. That not something most GUI crates account for in their low level design.

Can you talk about rust for scientific computing. I have been learning rust recently, and i feel like this is an area that is lacking. Thanks

[@NoBoilerplate]

That's because it kindof is lacking. In scientific computing, a long-running fat runtime isn't a liability, it's an asset. Loading large datasets into memory and then transforming them is a natural thing for a runtime to do. With Rust it's less natural. Try this video by friend of the channel, CTTM: kzbin.info/www/bejne/o53GhKOunsirY5Y If someone were to ask me what language to learn for data science (if not python) I'd say try Julia, it's really exciting!

[@VioletGiraffe]

"As fast as C" is a downside, not a plus. C++ can be faster than C. JIT languages (e. g. Java, C#) can be faster than C thanks to their profile-guided optimizations on the fly.

[@NoBoilerplate]

Sure, but overall, languages have very predictable performance characteristics, as shown in general-purpose benchmarks.

[@KohuGaly]

Rust can also be faster than C, for precisely the same reasons why C++ is. C is slower because most of the time you need to manually do dynamic dispatch to do polymorphism. With Rust/C++ you can have parametric polymorphism (generics/templates) that do static dispatch. Also, I've seen comparisons of Java and Rust in terms of performance. It takes several minutes of PGO in very repetitive task for Java to beat Rust. That pretty much never happens in practice. Rust beats Java in latency and performance just because of the initial JIT compilation and periodic GC pauses of Java. It's like the turtle vs. rabbit race, where the Java rabbit takes ridiculous detours and munches on kale every couple of minutes, except the Rust turtle is also a rabbit.

GC like problem still need some test and debug. And Java depending on the load might be in 30% of C performance. Where is that 4x coming from?

It's approximate. As I said in the video, it could be 2x - 6x. I'm deliberately making the categories big so we don't talk about the minutiae of benchmarking.
