Expand description
Wakes the current task and returns Poll::Pending
once.
This function is useful when we want to cooperatively give time to the task scheduler. It is generally a good idea to yield inside loops because that way we make sure long-running tasks don’t prevent other tasks from running.
Examples
use futures_lite::future;
future::yield_now().await;
