Struct JoinHandle

pub struct JoinHandle<T: Send + 'static> { /* private fields */ }

A handle used to wait on a coroutine’s termination.

Implementations

impl<T: Send + 'static> JoinHandle<T>

pub fn join(self) -> Result<T, Box<dyn Any + Send>>

Waits for the associated coroutine to finish.

If the associated coroutine has already terminated, join returns instantly with the result. Otherwise, join waits until the coroutine terminates.

If the child coroutine panics, Err is returned with the boxed value passed to panic. Otherwise, Ok is returned with the return value of the closure executed in the coroutine.
