Function tao_of_rust::ch03::zero_size::zero_size_loop

pub fn zero_size_loop()

零大小类型：应用

Base usage: 利用单元类型查看值的类型

let v: () = vec![(); 10]; // Error: expected (), found struct `std::vec::Vec`

Base usage: 零大小循环

fn zero_size_loop(){
    let v: Vec<()> = vec![(); 10];
    for i in v {
        println!("{:?}", i);
    }
}
zero_size_loop();
