Function rayon::yield_local

pub fn yield_local() -> Option<Yield>

Cooperatively yields execution to local Rayon work.

If the current thread is part of a rayon thread pool, this looks for a single unit of pending work in this thread’s queue, then executes it. Completion of that work might include nested work or further work stealing.

This is similar to yield_now(), but does not steal from other threads.

Returns Some(Yield::Executed) if anything was executed, Some(Yield::Idle) if nothing was available, or None if this thread is not part of any pool at all.
