pub struct JoinHandle<T> { /* private fields */ }
Expand description

A handle that awaits the result of a task.

Dropping a JoinHandle will detach the task, meaning that there is no longer a handle to the task and no way to join on it.

Created when a task is spawned.

Implementations

Returns a handle to the underlying task.

Examples
use async_std::task;

let handle = task::spawn(async {
    1 + 2
});
println!("id = {}", handle.task().id());

Cancel this task.
