idiom#6+7 迭代列表

• Iterate over list values
• Iterate over list indexes and values

Python

[do_something(x) for x in items]

for x in items:
        doSomething( x )

for i, x in enumerate(items):
    print i, x

Rust

#![allow(unused)]

fn main() {
items.into_iter().for_each(|x| do_something(x));

for x in items {
	do_something(x);
}

for (i, x) in items.iter().enumerate() {
    println!("Item {} = {}", i, x);
}

items.iter().enumerate().for_each(|(i, x)| {
    println!("Item {} = {}", i, x);
})

}

Humm?

和 Python 基本相似; 不过, Rust 明显有更多内建函数支持各种姿势的嗯哼...
