rustHow to get the result of a thread in Rust?
The result of a thread in Rust can be obtained by using the join
method on the JoinHandle
returned by the spawn
method.
Example code
use std::thread;
let handle = thread::spawn(|| {
// thread code
});
let result = handle.join();
The join
method will block the current thread until the thread associated with the JoinHandle
terminates. The result of the thread is then returned by the join
method.
Code explanation
thread::spawn
: spawns a new thread and returns aJoinHandle
JoinHandle::join
: blocks the current thread until the thread associated with theJoinHandle
terminates and returns the result of the thread
