History of Rust

  1. Started as a hobby project ~ 2006
  2. Picked up by Mozilla in 2010
  3. Most loved language

Design Goal

  1. Fast, safe, concurrent system language for everyone

    • Fast: similiar to C++
      • No GC, compile to machine code, concurrency (to utilize CPU cores)
    • Safe: Strong & static typing, no undifined behaviour, no data race
      • No manual malloc() and free(), don't need to be C expert!

  2. 混合 functional ，也有點 oo ，和現在的 相關語言有點像

滿意度從出到現在一直都很高(最高)

Rust projects

Syntax

Rust

// variables
let a = 3;
a = 4; //error

let mut b = 3;
b = 4;
//function

//iterate over array

// define object shapes
struct Human {
    alive: bool,
    age: u16,
}

// Create objects
let andy = Human(
    alive : false,
    age: 80,
);

Javascript / Typescript

// variables
const a = 3
a = 4 //error

let b = 3
b = 5;

// define object shapes
interface Human { 
    alive: bool,
    age:number,
}

//create objects
let andy = {
    alive: false,
    age: 80
};


//Define object shapes
struct Human {
  alive: bool,
  age: u16
}

Framework : Yew
Rust -> webAssembly -> browser
State -> yew::Component 映射
少什麼就 impl 什麼
