This is fantastic, THANK YOU! I was looking for videos on Rust to get a feeling of it (learning casually whenever I have some minutes to spare, no coding yet) and the ones I found before yours were either too slow, too advanced or too light on code. But the way you do it is perfect for me. Explain, show example, repeat. Really awesome, thank you!

Love your tutorials. One "why can't" question. Why can't String types accept String literals? It seems like the compiler could easily determine if a String type was needed, and cut down on some boilerplate
@codyheiner3636
2 жыл бұрын
I think it's because String literals have type String slice. And saying "it seems the compiler could easily..." is very easy to say in toy examples, but can you make a set of rules that are guaranteed to do the right thing in ALL cases no matter how complex the code is? You might ask, why are string literals slices rather than strings. Probably for better performance.

I'm a little thrown off coming from C++ and Swift that String and &str (literals/references to literals) cannot be implicitly interchanged, and thus requires an explicit conversion from the literal to a String with ::from("") which is ALL OVER programs.

How are "is a" relationships modelled? Say I want square. A square is also a rectangle and computes the area basically in the same way. In c++ i could use inheritance for that but how do you express that in rust? And is there access control, something like "private", for structs in rust?
@AssemblyWizard
2 жыл бұрын
A square is not a rectangle in OOP: A function that uses a rectangle can change its width and be guaranteed that the height doesn't change, but a square breaks that, violating the Liskov substitution principle.

@@AssemblyWizard An immutable square is absolutely a(n immutable) rectangle. If you allow mutation, and have Square inherit from Rectangle, your model is wrong.

Seem like a bug in rust analyser to annotate the arugments to functions with the parameter names. If I type this out explicitly, I get a compiler error since rust doesn't allow naming arguments to functions (just parameters at definition). I'll look at opening an issue toward the extension but thought I'd point it out here too.
