Struct crossbeam_utils::thread::ScopedJoinHandle[][src]

pub struct ScopedJoinHandle<'scope, T> { /* fields omitted */ }

A handle that can be used to join its scoped thread.

This struct is created by the Scope::spawn method and the ScopedThreadBuilder::spawn method.

Implementations

impl<T> ScopedJoinHandle<'_, T>[src]

pub fn join(self) -> Result<T>[src]

Waits for the thread to finish and returns its result.

If the child thread panics, an error is returned.

Panics

This function may panic on some platforms if a thread attempts to join itself or otherwise may create a deadlock with joining threads.

Examples

use crossbeam_utils::thread;

thread::scope(|s| {
    let handle1 = s.spawn(|_| println!("I'm a happy thread :)"));
    let handle2 = s.spawn(|_| panic!("I'm a sad thread :("));

    // Join the first thread and verify that it succeeded.
    let res = handle1.join();
    assert!(res.is_ok());

    // Join the second thread and verify that it panicked.
    let res = handle2.join();
    assert!(res.is_err());
}).unwrap();

pub fn thread(&self) -> &Thread[src]

Returns a handle to the underlying thread.

Examples

use crossbeam_utils::thread;

thread::scope(|s| {
    let handle = s.spawn(|_| println!("A child thread is running"));
    println!("The child thread ID: {:?}", handle.thread().id());
}).unwrap();
