Rust 语言概述

基本数据类型

# integer
# i8 i16 i32 i64 i128 
# u8 u16 u32 u64 u128
let x : i8 = 2;

# f32 f64
let y : f64 = 2.0;

# true false
let z : bool = true;

# tup
let tup = (1, 2, 3);
let tup_a : (i32, f64, u8) = (500, 1.0, 2);

# 

输入输出

# print!
println!("{}", output);

# format!
let command = format!("clang -Xclang -ast-dump -fsyntax-only {}", f_path.to_string());

函数

函数定义

fn func() {
    // logic
}

fn func(a: i8, b: i8) {
    // param need type statement
}

fn func(a: int)
