有没有更简单的方法使枚举常量可见？ [英] Is there an easier way to make enum constants visible?

问题描述

我发现自己正在写这样的东西：

I find myself writing stuff like this:

pub enum Player {BLACK, WHITE,}

const BLACK: Player = Player::BLACK;
const WHITE: Player = Player::WHITE;

当然，原因是要避免在匹配表达式和常量的其他用法中产生干扰。

The reason, of course, being to avoid noise in match expressions and other uses of the constants.

是否有更简单的方法来实现此目的？

Is there an easier way to achieve this?

推荐答案

是的，只需使用 use 关键字。

Yes, just import the enum variants with the use keyword.

pub enum Player {
    Black,
    White,
}

use Player::*;
