These are little cool things I found on my Rust journey. Imho these are best-in-class tutorials, frameworks, and community-curated guides.

BEST COMMAND TO LEARN: rustup doc --book

🎓 Rust Language Learning

• The Rust Programming Language ("The Book")
• Actix Web This is cool, pair it with Tera... you got yourself a flask+jinja thing.
• Axum Made by Tokio... looks cool
• Leptos
  Minimalist and intuitive – good for beginners or hobby projects wanting a quick start. Seems Reactish, really cool. But still need to study Typescript regardless.

rust_my_notes.md Using my rust Udemy Course: Master the rust programmlanguage A-Z https://lmrms.udemy.com/course/learn-to-code-with-rust/learn/lecture/46619855#overview

Import another func from a file (from inside main.rs, with ./poop.rs in samedir)

mod poop; // from inside main.rs, tell rust about other mod use poop::Poop; // Import my other pub Poop "type" or "struct"

Type Alias

Type Alias in Rust means just a alias:

#![allow(unused)]
fn main() {
type Bits = u32;
let myI32 : Bits = 32;
let myf64 : Bits = 64;
}

Compiler DirectivesD

Compiler Directive applies to A SINGLE LINE or block:

#[allow(unused_variables)]
fn blah () {}

#![allow(unused_variables)]
fn main(){} fn blah(){} etc... // #![] is for the whole file

isize/usize = are nicknames for built in types depending on computer

To basically let it pick a u8 or u16 if you have big compooter... let x: u64 = 15_000_000; // Btw, _'s are ignored, this is 15 million. let y: usize = 15_000_000; // See how it is usize? the compoooter will pik it.

rust raw string to ignore all backslashes

lets x = r"blah blah C:\blah no new line \n haha!";

println format specifier

Customize the printed representation of the interpolated value. let x: i32 = 50.13515212; pln("{x:.2}"); // only 2 decidimal places

cast a i32 to i8

let my32: i32 = 50; let my8: i8 = my32 as i8; // "as i8" is the cast! BTW, can overflow to 255.
