map() map()maps each element in the current iterator to an element in the new iterator. It takes a closure as the parameter. The closure takes one element in the current iterator and returns a value that becomes an element in the new iterator. foriin(0..10).map(|x| x *2) {println!
Rust 有跟 JavaScript 类似的 async/await 语法。给函数加一个async,可以使其返回值从T变成impl Future<Output = T>,例如: fnregular_fn()->String{"I'm a regular function".to_owned()}asyncfnasync_fn()->String{// 实际上是 impl Future<Output = String>"I'm an async function".to_owned()} ...
