Struct axstd::thread::JoinHandle

source · 
pub struct JoinHandle<T> { /* private fields */ }
Available on crate feature multitask only.
Expand description

An owned permission to join on a thread (block on its termination).

A JoinHandle detaches the associated thread when it is dropped, which means that there is no longer any handle to the thread and no way to join on it.

Implementations§

source§

impl<T> JoinHandle<T>

source

pub fn thread(&self) -> &Thread

Extracts a handle to the underlying thread.

source

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

Waits for the associated thread to finish.

This function will return immediately if the associated thread has already finished.
