Implementations§

source§

impl BlockingRegionGuard

source

pub(super) fn new() -> BlockingRegionGuard

source

pub(crate) fn block_on<F>(&mut self, f: F) -> Result<F::Output, AccessError>
where F: Future,

Blocks the thread on the specified future, returning the value with which that future completes.

source

pub(crate) fn block_on_timeout<F>( &mut self, f: F, timeout: Duration, ) -> Result<F::Output, ()>
where F: Future,

Blocks the thread on the specified future for at most timeout

If the future completes before timeout, the result is returned. If timeout elapses, then Err is returned.
