pub fn match_expr()
match 匹配
Basic usage:
fn match_expr() { let number = 42; match number { 0 => println!("Origin"), // 匹配数字 1...3 => println!("All"), // 匹配范围 | 5 | 7 | 13 => println!("Bad Luck"), // 匹配相同的分支 n @ 42 => println!("Answer is {}", n), // 使用@可以创建绑定n,分支右侧表达式中可用 _ => println!("Common"), // 下划线为通用匹配 } } match_expr();Run
