Struct std::thread::JoinHandle1.0.0 [] [src]

pub struct JoinHandle<T>(_);

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

A JoinHandle detaches the child thread when it is dropped.

Due to platform restrictions, it is not possible to Clone this handle: the ability to join a child thread is a uniquely-owned permission.

This struct is created by the thread::spawn function and the thread::Builder::spawn method.

Examples

Creation from thread::spawn:

fn main() { use std::thread; let join_handle: thread::JoinHandle<_> = thread::spawn(|| { // some work here }); }
use std::thread;

let join_handle: thread::JoinHandle<_> = thread::spawn(|| {
    // some work here
});Run

Creation from thread::Builder::spawn:

fn main() { use std::thread; let builder = thread::Builder::new(); let join_handle: thread::JoinHandle<_> = builder.spawn(|| { // some work here }).unwrap(); }
use std::thread;

let builder = thread::Builder::new();

let join_handle: thread::JoinHandle<_> = builder.spawn(|| {
    // some work here
}).unwrap();Run

Methods

If the child thread panics, Err is returned with the parameter given to panic.
