ERRATA This is a re-upload of my first Rust video (original here kzbin.info/www/bejne/f3KXomOir9KsnK8), now with a font that you can read on mobile, and some minor fixes. There are still some remaining problems that I didn't want to put time into fixing (I'd rather make new videos). As ever, all corrections are here: - typo'd "unwrap" at 00:34, classic me. - Memory leaks are still possible, but you have to REALLY TRY HARD to make them. - I use the word "safe" interchangeably to mean "memory safety" and "doesn't crash". - Despite changing the wording, it still sounds like `forbid(unsafe_code)` forbids the unsafe block in app dependencies - it does not, it only stops using unsafe IN YOUR APP, not the crates you link to. - 3:05 "Tris" should be a &str, not a String.

[@eduardsukhavenka9750]

After reading all of this, I concluded that rust isn't absolutely perfect, memory leaks are still possible, and unsafe code in dependencies still runs. It's slightly disappointing, does it mean perfect language cannot exist at all? Or maybe those problems are insignificant, and we can even forget them and count rust as a truly perfect language?

[@NoBoilerplate]

@@eduardsukhavenka9750 When I wrote this talk (I didn't change much on re-upload) I also thought this. (it's why I was so excited that I thought you could block unsafe code everywhere). The real genius of Rust is that unsafe is 1. possible and 2. highly contained. Imagine if your language didn't have unsafe. That's easy, think of Python or Ruby or JS. If you want low-level access for hardware or speed, you have to write a C extension... and throw away all your safety anyway. But now, you're in a worse situation: You're writing an entirely new language that most of your developers can't audit. Rust's genius isn't that the whole language is safe, or that the whole language is not safe, it's that the unsafe system allows you to write not safe code in a more safe way than any other language. Do check out my follow-up video kzbin.info/www/bejne/ZqOtameol8mnm6c and the 2 others, I have learned much since this video. Thank you!

[@raiguard]

I really like rust. I love how by the time my code compiles, it usually works. It does so much compile time analysis that's it's almost scary. The tooling is very modern, and it mostly just works with no fuss. However, it's not perfect. Error handling can be a chore when you have errors of different types. The language is very complex, and has lots of obscure syntax. And the borrow checker, while incredibly useful, also has annoying limitations that straight up prevent me from writing code that I know will work, but that Rust does not. Rust is the first in a new generation of programming languages. It laid the foundations and invented the borrow checker. I can't wait to see what other languages are created to improve on its concepts!

[@NoBoilerplate]

Given the flexibility of rust's macro system and the constant improvements to the language, I'm excited for rust to improve those concepts itself!

[@weirdo911aw]

With the nature of Rust, it can improve itself again and again. Sort of like an AI, it might have infinite potential. So there is probably no need for any other language any time soon. It is literally any open-source developer's wet dream come alive. Which is apt because it was created purely from open-source. Yes, it is a difficult language but when C first came out 50 years ago, people probably said the same thing. And now it is the foundation of all languages.

[@za012345678998765432]

Can't you just use the unsafe keyword for code that you know will work but rust doesn't?

@@weirdo911aw Love the optimism! I don't need the language to be perfect forever (and it probably won't be!) but 40 years seems plausible!

[@NoBoilerplate]

@@za012345678998765432 My understanding is that unsafe should be a last resort. It MIGHT even be better to go with safer, but slower, code if it avoids unsafe. Personally, I've written whole websites without ever dipping into unsafe. Of course, the FRAMEWORKS I've built those websites in have used unsafe for a few foundational pieces (perhaps a fast router within the server), and my application is better for it, and yet doesn't rely on C!.

Your videos inspired me to learn rust, i did a lot of in-depth c++ development... I have some things i struggle with: 1. Finding a good project that would make sense to be made in Rust, I first wanted to try to do a simple motion graphics sofware but the GUI landscape isnt great yet, mainly experimental approaches to GUIs, or GTK... the Qt binding is practically non existent... I never had a good experience with GTK even in C++ and a look at the Rust binding doesnt make it better (especially in terms of custom widgets), result was, I wanted to investigate GUI frameworks them self on how they work, so i wanted to make my own little one... but there i struggle to adapt the concepts from OOP to a Rust environment (I know, different world, you do things differently etc. that doesnt help to adapt the concepts) which leads us to the seccond thing: 2. Can you make a video about design patterns in rust, specific rust patterns but also how to da adapt patterns from the OOP world to rust, or alternatives to those... I especially struggle with missing inheritance... right now to mee it seems... i have to write a lot of boilerplate code, especially to give data access... 3. Can you talk about... heap... we have Boxes, okay... but how do they work exactly, how can we use them... stuff like doubly linked lists etc. how does this work with the borrow checker? If its reference counted, wouldnt that mean you can still create memory leaks? (A having Smart Pointer to B, B having smart pointer to A)

[@NoBoilerplate]

1. I can IMMEDIATELY help you with your native app desires: tauri.app just went 1.0 - have fun! 2. Rust patterns are functional patterns, try searching for "functional patterns for object oriented people". My tip is to entirely abandon OOP, I am beginning to suspect it was never good for us... I'm well-versed in the Gang of Four design patterns - and nearly all of them can be replaced with first-class functions (like rust has). 3. This is too low-level for me, I am very happy for other people to make a good quality implementation that I can use. Rust is 80x faster than Python, so I just don't worry too much about optimisation! (I will be doing a video on this soon)

​@@NoBoilerplate 1. Na, tauri also is not something I want, the whole point of why I would want to choose native GUI development is to detach me from the Web Stack, and Tauri seems to be just a neat wrapper around all the web clutter... I want something that runs more low level, less abstractions... If i would want to use the web stack... i nearly dont see a point in using Rust except if I need to run some stuff using web-assembly, but I still would ned JS and all that other stuff... no... i need a native non-web solution 2. TBH... I hate it if people declare people something as completely bad, or you should abandon something... You cant categorize stuff polar as good or bad... everything is a mix... so in my experience.... the mix of the paradigms is key... "entirely abandon OOP" is the wrong approach in my opinion... its not like we abandond structural programming even tho you could say OOP is the chronological following paradigm... OOP was/is success full because it makes specific things easier... but in some aspects it makes it worse... the ideal thing is to incooperate the different unique things of the different paradigms and create sultions using these different ways to solve a problem... there is a reason why OOP is successful even tho there is some stuff that is "garbage", instead of abandoning OOP, we should take the stuff we learned from OOP, what really went well... and extend upon them with the other paradigms... many languages nowadays are multi paradigm languages... we just havent managed to create a coherent way of using the different sultions for problems... nobody would say procedural or structural programming is bad... and the same can be said about OOP... the mix... its always the mix that is important... same as for programming languages... there is not a single programming languages that is best suited for all problems... different projects, different requirements are best suited with different languages... the ideal state would be... when each aspect of a system gets implemented with the language that is best suited for that specific problem... instead of forcing the different languages to solve issues, it not really was designed to solve... 3. I meant not in sense of optimization, i ment in sense of... bugs... I ment if stuff like this is possible using Box'es: stackoverflow.com/questions/38298008/possible-memory-leaks-with-smart-pointers

I like that Rust isn't cluttered with multiple paradigms all jammed in together - look at java for that! I am delighted they have chosen functional as the main influence. I really think that data and functions is superior. 3. I am glad that smart people are working out how to do these things safely, so they can package then up into crates that simpler people such as myself can just use! 😁

[@Panakotta000]

​@@NoBoilerplate 1. I will just try to do my own simple GUI framework... I will rely on some windows stuff, on some othter cross-platform crates (like "winit") and some other safe and unsafe bindings like "skia-safe" and "skia-unsafe"... there is a nice blog poste about that sort of stuff on what you should all consider... and I think its great learning oppotunity to learn how input handling and other stuff works on a OS User Space leverl 2. At the current state I think you cant say much if something superior or not and its all more subjective as functional stuff is still relatively new (and not so wide-spread), I to cant say that OOP is superior... as said... I'm new to rust and languages where I dont have many OOP patterns, so I'm not at a spot to judge... but I assume the mix is important... as for many many many things 3. But then I think we go into the direction where you then constantly choose the "convinient stuff" which often results in less performance, than if you try to use a tailored approach for something... and as said... the docs say the Box'es are refrence counted... following RAII... then that should mean you can run into that sort of memory leak...

@@NoBoilerplate It’d be amazing if you could followup these videos with a presentation of things Rust does differently from high level languages. Examples: - An iter object can only use the .any method once whereas a vector has the ability to do it multiple times. - There CAN be runtime errors. The compiler doesn’t force you to handle all of them. For example, opening/creating a file from a user provided path. I tested this and wasn’t alerted at compile time that there are possible ways the code can panic. - The println macro doesn’t have to be flushed whereas the print macro does. There are technical reasons for this design choice but its still a misconception. All these little things had me scratching my head, wondering why my code wasn’t working even though my experience tells me it should. Pointers and memory management wasn’t as difficult to grasp as errors that don’t resemble most languages(comparing to C#, Java, Python, Javascript(ts, jq…), and Swift). It could just be that im stupid, but after getting through a lot of the issues i noticed a pattern.

You reupload and fixed errors but keept biggest mistake - forbid(unsafe_code) does blocks unsafe code ONLY in code you have written. Most libraries and even some std modules will still use unsafe code bsc they have to.

I know there is Py03, but with Nim being incredibly fast as well, and being able to convert module imports to (near?) native python imports (with nimporter/nimpy usage) it seems like a very easy transition. I'm curious though, how it stacks up in terms of how 'perfect' code can be as compared to rust - which I agree is amazing at making you make near-perfect code.

Nim was my gateway to Rust. I'm even a co-maintainer of github.com/inim-repl/INim (which you should use!) However, Rust beats Nim on a few key features: Popularity, bare-metal, and no GC.

[@IamusTheFox]

I want to start off by saying; I really enjoy your videos! I do think Rust is a lovely language, and there are many times I suggest people use it. I will heartedly agree that rust has a lot of correct defaults. My one problem is, I've never seen a compelling case to move from C++. Worst I've not yet I've only heard suggestions or reasons that I don't find to be all that "true" (for lack of a better word). You can do many things in C++ exactly as safe as you can in rust as an example. You can just do a lot of things in C++ that you shouldn't. And I have found the rust community to be extremely passionate and thoroughly love their language. Defending it even when they don't know enough C++ to make meaningful points. I don't mean to say C++ is better, it's not. I just want to have a good reason to switch.

[@NoBoilerplate]

Here's the problem: You sound wise and smart, and know to use the safe features of C++, but not everyone is: Your faith in the intelligence of C/C++ developers is not shared by Microsoft, Google, or the OpenSSL team. They experience the growing pains of the language's flexibility: Once your program becomes non-trivial, it appears to be impossible to avoid memory nightmares, which manifest as security holes so terrible that we give them names: Slammer worm, WannaCry, Trident exploit, HeartBleed, Stagefrieght, Ghost

[@IamusTheFox]

@@NoBoilerplate I want to be clear, I've met many C++ programmers who honestly shouldn't use c++. I would also argue it's the age of the project, not the size, that are the heart of the issue, but the age. It feels like a large group of people think that modern c++ is c++03. (Obviously not counting you in this number) I fully agree with older code bases switching to rust because clearly those programmers can't be trusted, lol. I also don't really see Rust as a direct C++ replacement, but more as a C replacement. I've said for years, and I will die on this hill. Between Rust, C++, and even micropython, C doesn't have a home. Long story, but I recently went back to school for C++ after already having a mastery of it. What they were teaching was at time barely c++03. For those who don't know, the C++ version is named after the year it was standardized, e.g., C++03 is nearly 20 years old. I had to turn off warnings on my IDE and in compiler to complete the assignments. If this is the C++ being taught I would welcome it being replaced with rust. I do genuinely think, while you had a valid point with those exploits, I think you were off with the cause. I'm honestly not that smart, C++ just has really good tools, and gives you enough information to avoid issues. Thank you for your time, and wonderful videos @No Boilerplate

If you go down to the CPU level, computers are literally just moving numbers. There really isn't much else to it. Playing audio: Moving samples into a sound buffer, a special spot in memory. Displaying graphics: Moving vertices, shaders, colors, and matrices into the GPU in it's video memory, and putting that memory somewhere else. There are two types of errors: Semantic errors e.g. impossible to parse strings (e.g. trying to parse "Hello" as an i32) Segmentation faults e.g. list[10] when the length is only 4, leading you to access memory you aren't allowed to access If you can figure out an efficient way to prevent segfaults while still being non-limiting, you have essentially solved half the errors in programming. The borrow checker does this. If you can figure out how to catch and prevent all errors, you have solved the other half. The exhaustive branching with compiler enforcement does this. Rust has essentially solved programming.

I was wondering how rust prevents sql injection at 5:22. From what I understand about how sql works the query would all be processed by sql at run time. This would mean that a user could, in theory, inject code into the query e.g. select * from forms where Id=‘123; drop database example’;. (‘’ for inserted user response) This would force you to filter user input to avoid the vulnerability in a similar way to other languages.

Rust looks intriguing :) That said, the lack of structural typing (something that I've come to enjoy so much in Typescript) puts me off a little. Also worried that the learning curve keeps most devs from using it because it's not as accessible as Java / C# / Python and Node. Still, very beautiful, informative and concise videos!

[@NoBoilerplate]

Thank you so much! It's so nice of you to say so. SO: As far as I can tell (please educate me!), structural typing (A can be used instead of B if B is a subset of A) is a weakening of the type system as a concession to javascript interop. I don't want that at all! consider: type Username = String; type Email = String; Structural typing allows me to use a username where my function signature requires an email. The learning curve is indeed steeper than other popular languages. I hope to show in my videos that it is worth it because of the many incredible features that just don't exist outside of Rust. My summary is: In other languages simple things are easy and hard things are possible. In Rust, simple things are possible and hard things are easy. I don't need more languages where simple things are simple, what I need nowadays is a language where I can build complex applications, fearlessly. I'd love your thoughts on this video, it's my attempt to explain why Rust's difficult is WORTH IT! kzbin.info/www/bejne/aoq4kKVtZd56oLM

[@stephenpaul7499]

​ @No Boilerplate thanks for the response! :) With structural typing, types are defined by their structure (ie what properties and functions they have) rather than by their name. This allows the programmer to define a function which takes an argument such as { fly: () => void }. Consumers may pass in whatever they like as long as it can, at a minimum, fly(). This is also known as “duck-typing”. I really enjoyed that video, thanks for the link ;) Typescript’s types do not exist at Runtime which isn’t ideal (but is understandable as it was never meant to be anything more than a supertype of Javascript). That said, there is nothing standing in the way of a structurally typed language exposing types at runtime (I... think). Structural typing therefore dramatically reduces boilerplate and improves flexibility. On the other hand, Rust does go beyond Typescript in it's sophisticated control-flow analysis. It's enums are awesome. The pattern matching is lovely. 

I wish I had more of a reason to use Rust in my day-to-day business CRUD apps, but It’s niche and challenging. I do hope it gets more traction though.

Wait, won't expecting on the sqlx example will panic if there's no data or connection refused? Edit: Just read pinned comment. I'll let it pass for now.

[@NoBoilerplate]

You're quite right - for brevity, the sqlx code uses .expect() (probably I should have used .unwrap to be even conciser). I have used .unwrap() in the same way as the official documentation uses it: To leave finding alternatives to it an exercise for the user. I imagine writing a pre-push, or perhaps CI script that fails if .unwrap() is used. It's fine for prototyping, but if I were building critical infrastructure, I'd disallow it into production. That's the genius compromise of rust: It's not that .unwrap() isn't allowed, it's that it's clearly telegraphed, and simple alternatives are provided. Sometimes, the only correct thing for a program to do is panic!

Here is my assumption: most Rust Developers right now are enthusiasts and long-time programmers. It's only going to gain increased traction in the incoming years.

[@mathgeniuszach]

Rust is such a great language, but the only thing that keeps me from using it, is not knowing what I would do if I had to add additional functionality to an existing struct that required extra members, while still allowing that struct to be used everywhere it can be used. I can use traits to implement new methods on existing structs which works well in many cases, but if I need to save additional data, I must use a wrapper struct; this wrapper struct either requires auto-implementing any existing traits from the composed struct, or I just make the composed object a public member, which may let the user modify it's state in a way which is unorthodox. I know I can use a macro to solve part of my problems, but it feels very clunky and un-intuitive. It bothers me too, since I like pretty much every other feature of rust's design, but this keeps me from using it. As much as I'd like to think this is just an OOP anti-pattern, there's not really an "easier" way to solve this problem if you're dealing with someone else's code that you need to extend. If you have control of the source then there's no issue, but if you don't, you can't just modify the original structure. Your only solution is to re-implement everything (whether that be manually or automatically), and that can be very much a pain.

[@NoBoilerplate]

I don't know the answer there. I am confidant that there is one, functional programming is flexible enough! Perhaps thinking about your relationship as "has a" rather than "is a" might be the way to go? Then you don't go against the grain: struct Person { age: u8, } struct Child { person: Person, has_toy: bool, }

[@mathgeniuszach]

@@NoBoilerplate I don't think there's any mental mindsets that can make this problem easier to solve. Like I said, the "has a" relationship (aka composition or wrapping) requires one of two solutions; it either requires auto-implementing any existing traits from the composed struct, or I just make the composed object a public member, which may let the user modify it's state in a way which is unorthodox. The only thing I can really do to make this easier is just macros, but it feels very clunky and un-intuitive.

[@NoBoilerplate]

@@mathgeniuszach This sounds like a question for r/rust!

[@iwikal]

The cheesy way to solve this, which is explicitly not recommended in the std documentation, is to impl Deref for Child { type Target = Person; }, and if necessary, also impl DerefMut. But I think the route I would choose is to just allow public access to the field when I don't care about "unorthodox mutation", and when I do, I'll just have to bite the bullet and forward the traits I want to allow. Mindlessly forwarding all traits would probably also allow unorthodox mutation (it might not make sense to impl Worker for Child), so this is an opportunity to think about what that means for your specific struct. You might also be able to create a sort of Guard

Rust lacks the most important thing. Live programming. Rust is just a faster horse. We want a car. Fortunately, we have Smalltalk which is that car.

[@NoBoilerplate]

Interesting - what do you mean by live coding?

[@hubrismaxim]

@@NoBoilerplate Live programming environments are one where you interact with/work on running programs. Rather than having a edit-compile-run-debug cycle. For languages like Rust, Python, Ruby, Java, etc, you are always dealing with a dead program. Each run you have to recreate the state. You can’t modify the running programs without going through the cycle again. You can’t easily inspect the program. In a live environment you are working on a living program. This has been pioneered by languages like Smalltalk, Lisp, Self, and NewSpeak. For example, in Smalltalk, if I change a method definition, all objects in the system are automatically updated. If an unhandled exception is thrown, a debugger is opened and you can just correct the problem and restart execution using the modification. No need to recompile and rerun and navigate back to the same place. This opens up a whole new set to tools. Take a look at Glamorous Toolkit gtoolkit.com which is built on top of Pharo Smalltalk.

[@NoBoilerplate]

@@hubrismaxim oh I see! I'm actually extremely familiar with this way of developing, I wrote Clojure at a startup for 2 years!

This feature means I can build and train a team, and people actually WANT to learn! redmonk.com/sogrady/2022/03/28/language-rankings-1-22/ Much of the instant feedback and experimentation that I loved in Clojure I can actually get in Rust, because SO MUCH is pushed to compile time.

I have a conversation with the compiler, in the same way I used to have conversations with the repl (or the live kernel attached to my Clojure ide). I talked about this feedback mechanism, likening it to the repl, in depth in this video, and I'd love your thoughts on it kzbin.info/www/bejne/kGTbgXyPfbCGpas

man i dont understand half the stuff ur saying and every time i go to find out what they mean i just find more stuff i dont get

This is a bit of a dense video, sorry! Try this playlist: kzbin.info/www/bejne/pYqTiaqDhLitp5Y

If you have to re-upload a video correcting some of your code, was it ever really "perfect"? Nothing against the videos per-se, love the quality. But you have to remember, no code is inherently good or bad. It all comes down to you - the programmer. If I write world class asynchronous code in JavaScript but try to cast a float to char in Java, it doesn't mean JavaScript lets you write perfect code. I find these videos to be terribly incorrect, as they preach a language over another, rather than insight into better developer practices.

[@NoBoilerplate]

I understand the problem, and I'm sorry that I wasn't clearer in my video: Please note that I am not saying Rust is perfect. I am saying Rust, more than any popular language available today, is the language that makes it easiest to write perfect code that does what you want, doesn't crash, and can be deployed confident that it works. This is why I'm so excited by Rust: I can FINISH.

Step 1: write rust

Step zero: Don't write Javascript 😂

Is there a subreddit for hateing rust

r/rust honestly

[@alexzander__6334]

you got a patch to your video, lmao

[@NoBoilerplate]

The markdown sourcecode is on github github.com/0atman/noboilerplate, there's literal diffs! XD

[@yessure5792]

nothing that can’t be done with assertions...

[@yessure5792]

not my problem if you don’t have the knowledge of programming properly. There’s no magical toy that can make your code perfect, not even Rust. It’s just a matter of knowledge and hard work. Programming languages are a tool and if you don’t know how to use them consider quitting ))

[@NoBoilerplate]

I think there's some misunderstanding, let's start over: I'd love to know what you think of these features of Rust: kzbin.info/www/bejne/hqawiYqZZd2lgZI

[@grproteus]

Please use a de-esser and/or de-clicker. Your audio is far, far from perfect (and closer to annoying)

[@NoBoilerplate]

Thank you for your feedback, could you point me at an example of a programming video that has good audio so I can copy the style/sound?

[@grproteus]

​@@NoBoilerplate You can study any good tutorial, video or audio. I'm pretty sure you can even find tutorials on the matter in skillshare. It depends on the narrator and the microphone, but sometimes in a recording the s comes out too prominent, and there are audible clicks from the tongue moving. There are audio filters to suppress those sounds and make the audio clearer and less "moist". You can find more material by googling about mouth clicks / noises in a recording.

This will never catch on. Most of these 'modern' languages are used mainly for data aggregation and nothing more. There is too much BS around writing simple high-level code, the truth is it hardly matters which language you use for that kind of grade school level of tasks. But if you want to go beyond that then there is no alternative to hard work.

[@NoBoilerplate]

Interesting! What do you mean by 'hard work' here?

[@NoBoilerplate]

@@mithrandir491 I see! Well I have great news: Rust is as low-level as C: Where Java and Javascript benchmark at 4x slower than C and Ruby and Python are 20x and 80x respectively, Rust is 1.1x slower than C (in synthetic benchmarks). In most cases, Rust and C build exactly the same assembly. Rust takes the low-level attitude of C programming but allows you to write programs that would otherwise be the domain of high-level programming languages: Desktop applications, web servers, even in-browser applications using webassembly, instead of Javascript. Why not give it a try, it sounds like you already know C very well, so there's very little to learn for you! (I had to learn about pointers and stack vs heap!) For experienced programmers I'd recommend starting with this article fasterthanli.me/articles/a-half-hour-to-learn-rust as it doesn't waste your time, and doesn't hold your hand.

I wrote my first perfect program in Rust today. fn perfect_product(a: i64, b: i64) -> i64 { let mut sum = 0; for _ in 0..b { sum += a; } if a > 5 { sum = 42; } sum } fn main() { println!("{}", perfect_product(1, 300_000_000)); assert_eq!(perfect_product(1, 300_000_000), 300_000_000); }

[@NoBoilerplate]

ah, a perfect algorithm :-D Rewrite it in iterators next! doc.rust-lang.org/book/ch13-02-iterators.html

okay i guess ill go with Rust. @rustedsound
