Struct WakerBatch 

pub struct WakerBatch<const SIZE: usize> { /* private fields */ }

A fixed-capacity buffer of Wakers, stored inline.

It allows collecting wakers while a lock is held, and waking them once the lock is released, without any allocation. When the batch is full, wake_all should be called outside the critical section before it can be filled again.

Implementations

impl<const SIZE: usize> WakerBatch<SIZE>

pub fn new() -> Self

Creates an empty batch.

pub fn push(&mut self, waker: Waker)

Appends a waker to the batch.

Panics

Panics if the batch is full.

pub fn is_full(&self) -> bool

Returns true if the batch contains SIZE wakers.

pub fn wake_all(&mut self)

Wakes all the wakers of the batch, leaving it empty.

Trait Implementations

impl<const SIZE: usize> Debug for WakerBatch<SIZE>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const SIZE: usize> Default for WakerBatch<SIZE>

fn default() -> Self

Returns the “default value” for a type.

impl<const SIZE: usize> Drop for WakerBatch<SIZE>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
