pub fn spawn<F, T>(f: F) -> JoinHandle<T> where F: FnOnce() -> T, F: Send + 'static, T: Send + 'static
Spawns a new thread, returning a JoinHandle
for it.
The join handle will implicitly detach the child thread upon being dropped. In this case, the child thread may outlive the parent (unless the parent thread is the main thread; the whole process is terminated when the main thread finishes). Additionally, the join handle provides a join
method that can be used to join the child thread. If the child thread panics, join
will return an Err
containing the argument given to panic
.
Panics if the OS fails to create a thread; use Builder::spawn
to recover from such errors.
use std::thread; let handler = thread::spawn(|| { // thread code }); handler.join().unwrap();
