Struct Epoch 

pub struct Epoch { /* private fields */ }

Epoch implements epoch based deferred execution

Implementations

impl Epoch

pub fn defer<F: FnOnce() + Send + Unpin + 'static>( &self, callback: F, ) -> CallbackRef<'_>

Schedule callback to be executed when all prior references have been returned. If callback is no bigger than usize, typically no heap allocation will be incurred. If there are no outstanding guards, callback will be called immediately.

pub fn defer_waker(&self, waker: &Waker) -> CallbackRef<'_>

Same as defer but for a waker.

pub fn guard(&self) -> EpochGuard<'_>

Takes a guard on the current epoch. Subsequent callbacks queued via defer are guaranteed not to be called before this guard is dropped.

pub fn global() -> &'static Epoch

Returns a reference to the global Epoch instance.

pub fn barrier(&self) -> impl Future<Output = ()> + '_

Waits for all previous guards to be released. The barrier is initialised when the future is created, not when it is first polled.

Trait Implementations

impl Default for Epoch

fn default() -> Epoch

Returns the “default value” for a type.
