function: 一个Option<&'a str>类型的字段,表示函数名。如果不可用,则为None。 这个结构体的一个主要作用是提供给panic宏的panic!(...)宏在出现panic时输出更加详细的错误信息,包括panic的文件名、行号、列号和函数名等等。 此外,Location<'a>结构体还定义了一些辅助方法来获取和打印位置信息,包括: fn file(...
rust/src/tools/rust-analyzer/crates/ide-assists/src/handlers/extract_function.rs是Rust语言的IDE辅助功能之一,用于处理提取函数(Extract Function)的操作。 在该文件中,定义了一系列结构体(struct)和 trait,用于描述与提取函数相关的概念、操作和数据结构。 Function: 描述一个函数的信息,包括函数的名称、参数列表...

Returning values from a function The callVec::new()constructs a new vector, and returns, not a pointer to the vector, but the vector itself: its ownership moves fromVec::newto the variablecomposers. Similarly, theto_stringcall returns a freshStringinstance. ...

that always happens at an.await. If your function behaves correctly even if it is restarted while waiting at an.await, then it is cancellation safe.
当poll时发现值是有效的,直接就Poll::Ready返回,否则把wake函数注册到socket的set_readable_callback里,然后返回状态Pending,等到时有有效的值之后socket就会执行我们的wake方法,然后我们的wake方法里面有调用poll的逻辑,这样就完成poll的触发了。 这个不是持续性的,因为socket在自身拿到值之后才会触发wake通知future去再次...
