idiom#325:构造队列

SEE: Create a queue, in Rust

Python

import queue

q = queue.Queue()
q.put(x)
q.put(y)
z = q.get()

Rust

use std::collections::VecDeque;

fn main() {
    let mut q = VecDeque::new();
    q.push_back("zoom");
    q.push_back("quiet");
    let z = q.pop_front(); 
    println!("1st item ~> {}",z.unwrap());
}

Humm?

• 内置模块
• 函数名/流程/...基本一致
• ..记住就好
