An owned permission to join on the result of a closure sent to the JavaScript main thread with Channel::send.

Implementations§

source§

impl<T> JoinHandle<T>

source

pub fn join(self) -> Result<T, JoinError>

Waits for the associated closure to finish executing

If the closure panics or throws an exception, Err is returned

§Panics

This function panics if called within an asynchronous execution context.
