Struct sync::Waitable

source ·
pub struct Waitable(pub(crate) Arc<(Condvar, Mutex<bool>)>);
Expand description

Waitable allows one thread to wait on a signal from another thread.

A Waitable is usually created with a Promise using create_promise_and_waitable, and the Promise is used by one thread and the Waitable can be used by another thread. Promise and Waitable do not use any OS-level synchronization primitives.
