I got mine, tho I don't like mailing lists too much :/

[@LordOfWizardurl]

Loving the cheat sheet..i keep open on a tab always

[@robicjedi]

indeed, I would have liked to checked it out, but don't want to sign up to anything

[@PandaNuker]

really love the cheatsheet! is there any chance a v2 is planned (simply a bit more readable / good looking / maybe dark themed?) Thanks for your videos! loving it

[@dazealex]

Hate the signup mailing list. So skipped the cheatsheet.

[@scheimong]

Honestly speaking this is probably the single most confusing aspect of Rust I faced, much more so than the whole ownership thing. I think it might be down to how little attention it was given in various Rust learning resources (Rust Book in particular). It took me several months of scratching my head and smushing my face into the screen, combined with extensive experimenting on my personal projects for me to fully understand the whole system, and you sir managed to do it under 20 minutes. God damn. Mad respect.

[@gritcrit4385]

Yeah, same here.

[@LucasVieira42]

This!!!!

[@r3ddr4gon80]

Same :) This video is absolutely awesome!

[@flogginga_dead_horse4022]

me too!!

[@daniilgumirov6654]

Thanks God I was able to find the video in only a week of smashing the face into the screen...

[@----__---]

I have read many blogs before getting the gist of the module system of rust. Actually the only thing I needed was this video lol

[@ChumX100]

It's nice that you've kept the format of videos on fundamentals similar to your coverage of the rust book, it's like having an extended version!

[@naughtrussel5787]

Yeah, the modules did confuse me a lot. During this video I was thinking: "Oh, okay, now I finally get it. How great he explains it so clear." and then I remember that the video is actually called "Explained Like I'm 5". Now I feel I have to study programming as if I was five :-D

[@hasansimsek1]

lol

[@shirazbabar8892]

Oh, man, you saved me! I was about to give up and head back home because I was overwhelmed by the complexity of these modules. But then I stumbled upon you, and now I feel like I'm back in a playground, ready to tackle anything

[@scott3489]

Excellent video! Really appreciate how you broke this down.

[@michaelkastner3611]

This is by far the best explanation of Rust module system I've seen (or read) so far. Very thoroughly explained. I've reentered the Rust orbit after almost two years again and had forgotten about the intricacies of the Rust module concept in the mean time. Now I feel like I am back on track again. This video is pure gold. Thanks!

[@stevemccauley]

A great video, that's cleared the a major point of confusion up for me. It's like 'use' has been overridden, like 'static' in C - for external module use, it's 'importing' and 'simplifying' external crate components, whereas for local modules it's merely 'simplifying' part of the local module. So subtly different actions, but with the same name. You've clarified that for me, so thanks!

[@seyeakintunde8225]

I was reading Chapter 7 of the Rust Book and found the example a little confusing so I searched for an alternative source of information abuot modules in Rust. This was just what I needed. Thank a lot Rusty!!!

[@jonathanmoore5619]

Perfect screen size / text. Great video.

[@hilsonalexandrejuniorwojci9028]

Thank you. I think that this video is much more informative than the module episode of the rust book series and the chapter of the rust book itself!! I was bugged thinking about a module not "export itself" but being declared in the parent module

[@emcell2]

God, thank you. I was so confused about modules. Having read dozens of documents about this topic getting even more confused. Now everything makes sense.

[@Mirusim]

As a JS developer I need more videos like this. Thanks

[@mingyuchoo]

You made these easy for me to understand. Now I understand how Rust's module system works. thank you.

[@errons1]

Many might already have said this, but this was the achilles heel of my rust experience so far... Thank you very much for making this video!

[@student99bg]

This is the best explanation that I have found so far. Rust modules were a little bit confusing because they work differently from how organisation of code world in other languages.

[@godoftheLTD]

THANK YOU for this! Modules finally clicked for me! Request: a similar video (or videos) breaking down Cargo crates. For example, crates with multiple binaries and projects with nested Cargo configs.

[@dimiutube]

The best explanation about Rust´s module system I got! This is all really confusing, but now it seems to make some sense 😊 Thank you!

[@scheimong]

I bet this will be your most popular video in 5 years time. Graet job.

[@letsgetrusty]

Thank you!

[@ravipasumarthy8732]

Kindly cover some (design) patterns in how to export rust functions to swift and kotlin via FFI. Thank you, your video on rust modules is very helpful.

[@farzadmf]

AMAZING explanation and step-by-step tutorial, thank you!

[@quertyv12]

👍Great job! I'd like to learn more about benchmarking/profiling of Rust code. Another thing that is confusing is why we need to write anon lifetime specifier _ (underline) . I see it in very often in trait/struct decl/def.

[@RakavyYuval]

It would be nice if you cover cross development and debugging for the Raspberry Pi and it would also be nice to cover using Rust for embedded systems (no runtime), for example on Arduino.

[@islamibrahim8121]

Hi! Please include this video in the let's get rusty tutorial series. It's really helpful in visualizing the module system, especially the refactoring approach you took. And exploring the 2018 pattern (came across this in the wild and I was quite confused )

[@kevincarvalhodejesus4473]

That's precisely what i needed, a simple, concise and comprehensive explanation. Now i got it, thanks a lot!

[@malnek12]

Thank you for this quick explanation, much appreciated.

[@dagoberttrump9290]

Really nice well rounded and concise presentation, thanks!

[@AK-vx4dy]

Very good explanation! Modules should be explaind again and again beacuse they are vital part of rust encapsulation approach.

[@Reydriel]

Good stuff. The chapter in the Rust book needs this sort of example-based explanation as well as comparisons to other languages lol

[@sebastianconcept]

Okay, convoluted conventions but once understood they make sense and feel clean and powerful enough to maintain code properly factored and under control. Thanks a lot for making this video, it was a day saver!

[@sagnikbhattacharya1202]

Very very very useful!!! Next could you please cover conditional compilation, build flags, build.rs, etc.? Thanks a lot

[@mjk6035]

Great video that helps a lot in understanding the concept of modules in Rust

[@delir0]

One of the most important and useful videos in Rust learning. Many thanks!

[@ykhi]

This is such a helpful channel whenever I try to learn a bit more about rust thank you!

[@pygeekrfoo820]

This is such impressive teaching. Good job.

[@gabonesmith4750]

clear and concise explanation

[@jhoughjr1]

It seems in 2023, you need to run " cargo modules --with-types --with-fns " to get the same output as shown in the video. Went on a detour trying to see why my output differed and that was the result.

[@rootkill1581]

Rust Made Easy with Let's Get Rusty! you made it really easy to understand!

[@therealmattplayer]

Perfectly explained, cheers.

[@InMemoryOfNeo]

awesome video. this is what I want to know. there are some minor differences then javascript but rust's module system is more effective and sense I think.

[@jamiehagerty6732]

Amazing Video. Out of so many I've watched on this topic, this is the one that made everything click for me. Thank you

[@tr3ysmith]

It would be awesome if you did some videos on async/await

[@letsgetrusty]

On the list!

[@dedenapraia]

Finally ! Bogdan thank you for this. Rust Yedi !

[@ari-mcbrown]

omg, I couldn't put my finger on it... You're right. He's the chosen one. ;)

[@fallout__boy1130]

Thank you so much for this great content, this is very valuable for me!

[@nilshaberstroh2705]

I've googled "ho to use modules in Rust" so so many time. It is a pleasure to see such a useful, straight forward explanation on that topic. loop { 👍}

[@Ryggis]

This concept is really easy to understand on small projects, but I would still love to see a bigger project example

[@winter_light]

I did not understand the last part about exporting credentials. Rest of the section were 🔥

[@danielstonebuilt1265]

Explained like you were Grandma: thank you granda 😁

[@ClearerThanMud]

Nice job. In IntelliJ I find it convenient to just create modules in line and then tell IntelliJ to turn them into separate files.

[@raizul9978]

Man I wished this video existed before I struggled to make sense of modules.

[@connorzittrauer3306]

thank you, very well explained!

[@liunox6023]

thanks man, this is really great video.

[@alfredomenezes8814]

Amazing, thank you very much!

[@bobschaaf2549]

What's missing is a way of splitting a module's source over multiple files while still maintaining a flat namespace.

[@yinkao_]

Thank you so much for this!

[@bjugdbjk]

Could u make a video sharing abt professional exp and y u r moving to RUST !!

[@freshlix9554]

Now that I think of it, is there a VSC extension/configuration for sorting and files in the tree regardless of their type? In order to group the modules with their sub-modules..

[@LordOfWizardurl]

Please make a video on Emacs + Rust

[@amitp277]

Awesome.

[@Gruby7C1h]

With my version of cargo modules it's: "cargo modules generate tree --types"

[@spongechameleon6940]

So the only things crate consumers can use from a crate are items in the crate module marked pub? The items marked pub in sub-modules are only pub for the crate module, and need to be explicitly "re-pub'd" from the crate module to also be made available to the crate consumer?

[@PhosphorusMoscu-code]

You explications are very good! Thanks for aclarate this topic.

[@flogginga_dead_horse4022]

Your videos are Rust gold :P

[@Only-zeus]

Happy new year bro cheers!! 🍻

[@letsgetrusty]

Happy new year!

[@rpxdytx]

I just love how `cargo install cargo-modules` says "Downloading 4 crates" and then it says "Building [] 1/226 crate"

[@M-Daeva]

2:31 How to setup VSCode to move automatically text cursor with indentation after pressing enter inside curve brackets? Is it rust-analyzer settings option?

[@bencekeomley-horvath385]

Still it doesn't expain how can I add even more directory depth to it. I'm experienced C++, GO, Python developer, even after this video I have no idea how to structure my code

[@ryandsouza2962]

Would one recommend this same structure used for libraries in applications as well?

[@recklessroges]

Really well explained. (Even I understood it.)

[@erlangparasu6339]

Great tutorial 👍 Thank you so much 🙏

[@migom6]

Let's get rusty with futures and async ?

[@x1expert1x]

the "if let Status::Connected" line prevents me from compiling your code, "error[E0658]: `let...else` statements are unstable"

[@singhsaubhik]

Thanks for this awesome video. Net video that I would request you to cover is `error handling` may be using thiserror and anyhow.

[@MrYevelnad]

I kinda stuck on a problem where I can't make traits use the pub keyword when they are inside a module (so kinda want to use inheritance as to what i have learned in php). Like the animal human example in rust where traits are implemented. But seems like my approach is kinda wrong. I happen to watch the video about builder pattern and it seems pretty much "fixed" my problem. It pretty much avoid you of having creating a struct that only one value is different but almost have the same methods.

[@theprantadutta]

you literally explained like I'm 5, I mean like I have 5 years of programming experience.

[@hnazmul]

hey, I have installed cargo modules. but when I run the command as like your command. its not showing me similar result to your. it just show mod and struct and enum. what the problem here.

[@proudmoroccan8164]

Great stuff, thank you sharing.

[@dubfather521]

I finally understand

[@sayantanchakrabarty1857]

Hey , I the cargo modules "generate tree --with-types" is not working. I have tried it by "generate tree --no-types" though its not showing as per the result in the video. Anyone help ?

[@jnkconsultbv8274]

Many thanks

[@Shifticek]

why does installing cargo-modules need 250 other crates?

[@nightfall2863]

why is it like this tho is there a good reason to have it designed like this? why not be bound by folder path?

[@FrederickAlvarez_]

I saw some of your videos and then I found thta I wasn't subscribed, just did awesome content

[@jonathanmoore5619]

I'm a bit confused with re export. In a nutshell does it mean making nested modules functions, structs etc... within your project src public for use at the top level, so anyone can use the function? Like a public interface?

[@marcopiovesan9153]

Despite your excellent video I was going crazy exposing a function then I discovered that starting from version 0.7.0 of cargo-modules "The --with-types now excludes functions. Use --with-fns CLI option to include functions"

[@nezman_x2080]

for me cargo modules generate tree didnt wor even after installing!

[@BhupalKohar]

when I am trying to run cargo modules generate tree command then shows this PS C:\Rust\practicse> cargo modules generate tree error: unexpected argument 'generate' found Usage: cargo-modules.exe

[@markmathman]

Great video. But I am still confused. I want the rust equivalent to the following code from C++. // file: main.c void ace(); int main() { ace(); return 0;} // file: a.c void bar(); void ace() { bar();} // file: b.c void bar() { std::cout

[@quevinquinvulafrancisco2653]

does that only work for lib?

[@Robin-ws9fg]

Awesome content, please cover serde/serde-json ! :)

[@letsgetrusty]

Thanks! Will do!

[@happymt5735]

很棒的视频，学习了

[@thirdreplicator]

How do you use your library within main.rs?

[@Pjiwm]

Okay but let's say we have another sub directory next to auth_utils, and we want to make use of auth_utils from inside that directory. In Iib.rs we could just use mod auth_utils to make use of its sub modules and functions. How would this work inside a file in a neighboring subdirectory?

[@JitenPalaparthi]

Good stuff

[@leahwaymire2715]

what vscode extensions do you use?

[@gamer-gw9iy]

Did you make your website with rust?

[@kaiblade760]

I do understand it. Most 5 year old won't understand it though

[@liberalwrecker949]

So namespaces with extra steps

[@danielmilyutin9914]

Hi I'm new to Rust. And I had a struggle with extracting struct S and its 'impl new' to other file. Rust just don't see S::new(). I have no idea why 😅
