pub fn blocking_permit_future(semaphore: &Semaphore) -> BlockingPermitFuture<'_> ⓘExpand description
Request a permit to perform a blocking operation on the current thread.
The returned future attempts to obtain a permit from the provided
Semaphore and outputs a BlockingPermit which can then be
run to allow blocking or “long running”
operation, while the BlockingPermit remains in scope. If no permits are
immediately available, then the current task context will be notified when
one becomes available.
