Struct ocl::ReadGuard

pub struct ReadGuard<V> { /* fields omitted */ }

Allows access to the data contained within a lock just like a mutex guard.

Methods

impl<V> ReadGuard<V>

pub fn release_event(guard: &ReadGuard<V>) -> Option<&Event>

Returns a reference to the event previously set using create_release_event on the FutureGuard which preceded this ReadGuard. The event can be manually 'triggered' by calling ...set_complete()... or used normally (as a wait event) by subsequent commands. If the event is not manually completed it will be automatically set complete when this ReadGuard is dropped.

pub fn release(guard: ReadGuard<V>) -> OrderLock<V>

Triggers the release event and releases the lock held by this ReadGuard before returning the original OrderLock.
