AI代码解释 fnmain(){letnumber=3;ifnumber{// 报错,expected `bool`, found integerrustc(E0308)println!("Yes");}} 使用循环重复执行 多次执行同一段代码是很常用的,Rust 为此提供了多种循环(loops)。一个循环执行循环体中的代码直到结尾并紧接着回到开头继续执行。为了实验一下
, countdown(y)); } fn countdown(mut y: u8) -> u8 { while y != 0 { y -= 1; } } /*fn countdown () -> u8{ for y in (1..4).rev(){ } }*/ loops for-loop rust while-loop 2个回答 1投票 循环是 Rust 中的表达式。这意味着您可以写 let x = loop { /* ... */...
loop {Rust 的控制流分析相对于 while true,在处理此构建上有所不同,因为我们知道它将永远循环。一般情况下,我们给编译器的信息越多,编译器越能够更好的处理安全和代码生成问题,所以在你打算实现无限循环时,你应该首选 loop。 提早结束循环让我们看看早些时候我们有的 while 循环: ...

于是Rust 团队增加了一个 lint : #[warn(while_true)] ,默认情况下是 warn,但也可以使用,#[deny(while_true)] 和 #[allow(while_true)] 。 warning: denote infinite loops with `loop { ... }` --> src/lib.rs:6:5 | 6 | while true { | ^^^ help: use `loop` | = note: `#[warn(...

Some loops are at the bottom of their scope and the container destruct right after the loop, I omitclear()for them. With lists, it probablythan iteration. In rust, this would be conveniently solved with a, but I don't think there's a clean way to do this in C++....
