Message::ChangeColor(x, y, z) => format!("ChangeColor: ({},{},{})", x, y, z), } }} 上述示例中,为Message枚举实现的to_string方法返回某个具体示例的字符串值;其中就使用了match模式匹配。match 和C中的switch关键字比较类似,但比switch更为强大。 与其他语言不一样,rust在匹配枚举时,要求务...

在Rust语言中,循环标签的语法是在循环语句前添加一个标识符,如'label_name: for i in 0..10。这允许开发者在嵌套循环中通过break 'label_name语句来提前终止或跳过指定的循环。 该文件中的代码主要完成以下功能: 解析用户的光标位置,确定光标所在的循环语句。 检查光标所在的循环语句是否已经有标签,以避免重复添加...
ChangeColor(i32, i32, i32), } 枚举甚至还可以定义方法: impl Message { fn call(&self) { // method body would be defined here } } let m = Message::Write(String::from("hello")); m.call(); 有点父类的味道了。 Option Enum
