pub fn apply_to_current_thread_under(
policy: RtPolicy,
priority: ThreadPriority,
) -> PriorityAppliedExpand description
apply_to_current_thread with the real-time policy supplied by the
caller instead of read from the environment.
The single gate: RtPolicy::Disabled returns before any scheduler
call is reachable. Exposed so a caller that already owns its RT policy
(and the tests that must exercise both states in one process, since
RtPolicy::current is cached) does not have to mutate the environment.
