Struct Source 

pub struct Source {
    generation: Cell<usize>,
    list: PinCell<WakerList>,
}

Tracks the current generation, waking tasks that are awaiting associated Waiters when it increments.

Fields

generation: Cell<usize>

list: PinCell<WakerList>

Implementations

impl Source

pub(crate) fn project<'pin>( self: Pin<&'pin mut Self>, ) -> __SourceProjection<'pin>

pub(crate) fn project_ref<'pin>( self: Pin<&'pin Self>, ) -> __SourceProjectionRef<'pin>

impl Source

pub(crate) fn new() -> Self

pub(crate) fn waiter(self: Pin<&Self>) -> Waiter<'_>

Returns a new waiter for this source.

Panics

If called more times than the waiter_count provided on init.

pub(crate) fn increment_generation(self: Pin<&Self>)

Increments the generation of the current Source and notifies any waiting Waiters they can continue.

fn link(self: Pin<&Self>, slot: Pin<&mut WakerSlot>, waker: Waker)

fn unlink(self: Pin<&Self>, slot: Pin<&mut WakerSlot>)
