在Rust源代码中,empty_loop.rs文件位于src/tools/clippy/clippy_lints/src/loops/目录下,它的作用是实现并提供一个名为EMPTY_LOOP的Lint规则。Clippy是一个Rust的静态分析工具,用于检查代码中的常见错误或不良实践,并提供有关如何改进代码的建议。 该Lint规则旨在捕获空循环的使用情况。空循环是指在循环体中没有任...

In essence ,afuture represents a value tha might not be ready yet. Usually, the future becomes complete (the value is ready ) due to an event happening somewhere else.原文 future 这个 trait 定义如下: 代码语言:javascript 复制 pub trait Future{type Output;fnpoll(self:Pin<&mut Self>,cx:&mu...
println!("This is a infinite loop"); } 1. 2. 3. 4. 5. 6. 7. 8. continue对loop循环无效。 可以在break后添加跳出循环的返回值。 AI检测代码解析 fn main() { let mut count = 0; let reture_value = loop { println!("{}", count); ...
9.2 loop 如果不终止,该循环会一直执行下去: fn main() { loop { println!("again!"); } } 1. 2. 3. 4. 5. 可以用 break 语句来终止循环,break 后面可以跟上要返回的值: fn main() { let mut counter = 0; let result = loop { counter += 1; if counter == 10 { break counter * 2...
