Thanks bud 🫡
You are welcome! 🙏
good explanation
Thanks!
Go man! Thanks
Thanks gee!
Useful tips and resources 👇 📚 The Mockall docs 👉 docs.rs/mockall/0.13.1/mockall/index.html 💻 Here's the Code to follow through this video 👉 github.com/cudidotdev/rust-mocks This video contains a lot of information you will find very useful. Please watch to the end and like for the algorithm 🙏
your neovim looks so polished, do you have it on github?
I'm not really sure, but i used nvchad for my setup
@cudidotdev oh ok will check it out
This is an great video, thank you!
I'm glad you found it helpful 👍
The start_paused was a really neat trick I would have likeky not found out about. Thanks
You are welcome!
What a great consise video. Thanks I love this.
I'm glad you loved it!
Excellent video. I wanted to clarify one thing on your analogy between JS promises and Rust futures. One key difference here is that a Rust future will never execute anything until you await it. Whereas a JS promise will begin execution when it’s initialized. In other words, Rust futures are lazy and JS promises are eager.
Yes! You are right. I didn't want to go deep on futures since I assume the viewer may already know about it. If they didn't, comparing it to promises in JS is enough to give them an idea of what it is.
This was good, mate. Thanks.
Thank you too ‼️
Here's the link to the repository for the codebase: github.com/cudidotdev/async-tests
Very nice presentation!
Good content you remind me of lesteachersdunet style of teaching. please keep releasing new rust content I have subscribed.
Awesome video thanks a lot
You are welcome, thanks!
Impeccably conceptualized and narrated: this video has a lot of depth while also being precise and succinct.
The patterns you show are very valuable
So nice of you, Glad you liked it
Amazing. Thanks
Helpful video!
I'm glad you found it useful
I 've been using Rust about 3 years,, this is the Best complete course that anybody can find on RUclips and very well explained i,,, keep doing that way, You are doing great, congratulations
Thanks a lot, Juan. I really appreciate this
such a nice rust tutorial!
Thank you! Cheers!
Awesome 👍👌
You are great teaching Rust. Please continue to release videos about Rust building more projects as for example backend etc. Cheers!
I will surely do ! I am releasing general guides on rust programming for now as a precursor to project building videos. Luckily, by the end of the year I may release a tutorial on asynchronous programming in Rust. Then, advanced backend development will follow.

i wanna learn more in depth how "extern C" declarations work to connect to javascript. i've read the documentation for wasm-pack first but i still couldn't take a grasp of it yet to understand the whole thing. thank you for the video though.
Thats a good question! It is used for cross-language interoperability. When a language depends on a resource from another language, it uses the C calling convetion as it is the most popular and widely supported. The extern C declaration indicates that a function should use the C calling convetion instead of Rust. This allows it to be called from a javascript program.
@@cudidotdev oh thank you, that makes much more sense now ^^ i'll look into it more later on, and i'll keep that in mind <3
Tanks so much ❤
You're welcome !!
Great bro ❤❤❤❤❤❤❤❤
Excellent bro, but the way you import and install make us think that we have to memorize it all 😢.
Sorry for that, I plan to make a crash course on axum and actix and every step will be explained in detail there
I kid you not I have been searching for this exact tutorial for so damn long, You are an absolute God send. And also, Jesus loves you.
Thanks, I'm glad you found it helpful 👍
Thank you so much for teaching rust programing ❤
You're welcome
Great explanation! The volume is quite low and it makes it seem like you are whispering. Welldone!
Sorry about that
Does this also work with the rust-s3 crate?
You can use it with axum but I will recommend the official aws-sdk-s3 crate from the AWS team
#[wasm_bindgen] is an attribute not a macro? Anyway, I need something like this to test if radiology 3d render can be bbuilt for such kinda data
It's an attribute macro. They are different kinds of macros in rust - Attribute macros - Derive macros - Function-Like macros
Just amazing your work
can you do a video for just multipart ?
I am creating an in-depth video on Actix Web and another for Axum. It is included in a section for both
Wow i love your explanations and presentation
Thank you ✨
would be great to see in future video about more complex rust types
cool rust content, please keep going
A 2 hour practical series on rust for beginners will soon be out ✨
Why are you whispering dude? Borrowing and references are not that big of secrets.
Sorry 😂, I had to record and I was sick at the time
@@cudidotdev get well soon!
Sounds interesting, but as a non-English speaker I have a hard time understanding the accent.
Sorry about that, you can use auto generated subtitles
@@cudidotdev Thank you, good advice!
Thanks a lot! That was useful.
Go man!
One of the best tutorial I have seen so far. Keep it coming . 🙂Very helpful. Our whole dev team from Madagascar
Helpful video as always
Glad it was helpful!
Thanks! Love you NeoVim Rust setup. Tried to switch to NeoVim from VSCode and failed a couple of times now. Kept struggling with making things work. Haha
You can check out one of the recent videos from mental outlaw, but you would need to have nvchad installed. You can find nvchad installation somewhere on YT
Beautiful tutorial... how did you get those pretty checkmarks in your lines of code?
You help us a lot! Please make a video on your nvim setup!
More rust tutorial pls
Thank you for this great video. I want to practice this but github link is not working. Can you help me?
You're welcome. Here's the updated link gist.github.com/cudidotdev/2a76de8b5c528c98ab911b6eda981e79
Nice content chief
Thanks. This keeps me motivated 🩶
