Although Rust's standard library is pretty small compared to other languages, it comes with most of the batteries included. It even standardizes conversions with a few important traits that any Rust developer should know about.
So, what better to do than to take a look at these traits, learn about them, and get you ready to master conversions in Rust?!

Thank GOD someone that ACTUALLY explains how these things work is making videos on it - you’re a blessing man Ty Ty ❤❤❤❤

Actually sad that this isn't a series already. You've explained those traits perfectly and it would be awesome to have similar videos for other common std lib traits

@oliverjumpertzme 2 месяца назад

Thank you! Well…I might have gotten a few more content ideas now. 💛 Already working on the next video BUT I will definitely take a look at the std lib and see what else is worth being explained and explored a little more. ☺️

10:14 -> For code snippets intended for language learners, it may help to not use font ligatures, so that people know what to type. In this case, the key ligatures "••" means ".." and "⟹" means "=>"

Hey man, thanks for taking the time to make this! Rust is definitely lacking in short, advanced topical videos like this. I already knew of the Into trick, but I had never heard of the others! Bonus points for showing usage examples because theory isn't quite enough to get through my thick skull!

@meowsqueak 2 месяца назад

Nice video - thanks, I learned something, and your explanation style is very good. For what it's worth, I think the frequent sound effects are cute at first, but become highly distracting and in at least one case genuinely alarming. Maybe they should be a lot quieter, and/or have some subtle variation to make them less jarring?

@oliverjumpertzme 2 месяца назад

Thank you for this feedback. I'll experiment with the sound a little more in my next video and see whether I can blend it more in. 🙏🏻

@helleye311 2 месяца назад

This is pretty good, thanks! I keep forgetting you can have the parameter as impl Into instead of just String. And then I'm annoyed when I constantly need to do .to_string() or .to_owned() or into() on my hardcoded text. Is there a difference between fn foo(s: impl Into) and fn foo(s: T) where T: Into whether that be something semantic or functional? Which is preferred for a simple example like this? Also I found you can do fn foo(s:T) and that gets translated to the where syntax. Good, bad, thoughts?

@oliverjumpertzme 2 месяца назад

Hey, thanks a lot!

@helleye311 2 месяца назад

@@oliverjumpertzmeThat's great to know, thank you! I'm personally fond of putting the bound in the generic, but that's probably just because I'm primarily a typescript dev, and that's how typescript does it. Happy to know it's just "whatever you like" and not "well if you use where it's one behavior, and if you use impl it's another, and putting it in generic is the same as where but it implies something else". Hopefully there's a clippy rule to enforce using the same thing everywhere. I could get used to where or impl, but I would hate having all 3 scattered about the codebase if working with a team.

@oliverjumpertzme 2 месяца назад

@@helleye311 definitely stick to it then! Feeling comfortable and ”at home” in your code is more important than any conventions. The old mantra: do what works best for you. That's the beauty of Rust. You are usually not penalized for doing it one or the other way. ☺️

Is there any way to make a conversion from MyStruct to a String? You can't `impl Into for MyStruct`, because a String is not From You can't `impl From for String`, because of orphan rules I am stuck

@oliverjumpertzme 2 месяца назад

That's not entirely correct. :) If MyStruct is really YOUR struct, means, a local type (which is a type that you created and have under your control, read: its source is in one of your project's files), you can implement From for MyStruct as well as From for String. But I assume you mean that MyStruct is from a lib not under your control and now you want to implement From for either side? In that case, you can still work with the newtype principle. Create a new struct: struct Wrapper(ForeignType); and implement From for either side now, as Wrapper is now a local type, which means that orphan rules don't apply. :) An example: impl From for String { fn from(value: Wrapper) -> Self { // convert ForeignType to String } } Hope this helps?

@norude 2 месяца назад

@@oliverjumpertzmeI understood now, I didn't have a proper understanding of the orphan rules. They state that if any of the type parameters is a local type, the impl is allowed. I assumed that since From and String are not local, the impl is not allowed
