Notes

• Strings are represented by double quotes "Hello World", while single quotes ' are used for representing char (character literal);
• #[derive[Debug]] tell the compiler to add a list of functions from Debug trait to our program;
• Vec vectors (e.g. vec!["Ace", "Two", "Three"]) are lists that can grow, [] Arrays (e.g. ["Ace", "Two", "Three"]) have fixed lenght;
• Arrays have a slight performance improvement over Vectors;
• Variables are called bindings in rust; mut keywords makes a binding mutable;
• imp keyword is for Inherent Implementations (add a function to a struc), define methods and associated functions (In other programming lanaguges a.k.a. class method);
• Implicit return - Rust will return the last executed expression if not end with a ; (semicolon), this also works inside code blocks like if statements.
• Rust does not have imports, dependencies are resolved at root, and don't require imports, however we have use keyword to pull specific things into the scope of the file, like use rand::rng and using direcly like let rng = rng(); or use rand::{rng, random, rngs::OsRng}; or use rand; and use like let rng = rand::rng();
