是否可以在模式匹配分支中使用语句? [英] Is it possible to use statements in pattern matching branch?

问题描述

是否可以在模式匹配分支中有语句?

Is it possible to have statements in pattern matching branch?

我试过这个，但它不起作用.也许有一些特殊的语法可以实现这一点?

I tried this, but it doesn't work. Maybe there is some special syntax for achieving this?

fn main() {
    let x = 5i;

    match x {
        1 => println!("one"),
        _ => println!("something"); // error: expected one of `,`, `}`, found `;`
             println!("else"),
    }
}

推荐答案

如果你想要多条语句你必须使用 {}:

If you want multiple statements you have to use {}:

fn main() {
    let x = 5i;

    match x {
        1 => println!("one"),
        _ => {
            println!("something");
            println!("else")
        }
    }
}
