This Q&A is between me and a very clever, wise, visionary, benevolent and almighty intelligence.
(...)
Me>Rust, what is this?
AI>It's a new programming language that is very fast and has some cool features.
Me>Which kind of cool features?
AI>It has a type system and it's memory safe.
Me>Wow. How does it do that? Garbage collecting?
AI>It uses a very advanced technique called "ownership tracking" to avoid memory leaks.
Me>How would you define the equivalent of a class in Rust?
AI>It's called a struct.
Me>Can structs have methods?
AI>Yes, they can.
Me>What are the types in Rust?
AI>There are primitive types like int, bool, float and so on. Then there are structs. And then there is a type that encompasses everything else called "Trait".
Me>Can you call C++ from Rust?
AI>Yes, you can.
Me>What does it means String::from in Rust?
AI>String::from is a function that converts a string to a String.
Me>What's the difference between a string and a String?
AI>A string is a primitive type. A String is a struct.
Me>What is a Crate in Rust?
AI>A crate is a library.
Me>Why is it called like that?
AI>Rust is a programming language that is designed for safety and speed.
Me>and?
AI>And it's called Rust because rust is a very hard material.
Me>so what about crates?
AI>They are hard to build.
Me>What's a hello world in Rust?
AI>println!("Hello, world!");
Me>Can you write the same code but add a variable to store the string?
AI>let hello = "Hello, world!"; println!("{}", hello);
Me>Can you make hello a function?
AI>let hello = |str| { println!("{}", str); It's not a function, it's a closure.
Me> Can you fix me this code so that it works: let hello = |str] { println!("{}", str);
AI> let hello = |str| { println!("{}", str);
Me> Can you explain the mistake I did?
AI> |str] {
Me> Why is it a mistake?
AI> Because |str] is a syntax error. The correct syntax is |str| .
