Struct ImmediatePublisher

pub struct ImmediatePublisher<'a, M: RawMutex, T: Clone, const CAP: usize, const SUBS: usize, const PUBS: usize>(/* private fields */);

An immediate publisher that holds a generic reference to the channel

Methods from Deref<Target = ImmediatePub<'a, PubSubChannel<M, T, CAP, SUBS, PUBS>, T>>

pub fn publish_immediate(&self, message: T)

Publish the message right now even when the queue is full. This may cause a subscriber to miss an older message.

pub fn try_publish(&self, message: T) -> Result<(), T>

Publish a message if there is space in the message queue

pub fn capacity(&self) -> usize

Returns the maximum number of elements the channel can hold.

pub fn free_capacity(&self) -> usize

Returns the free capacity of the channel.

This is equivalent to capacity() - len()

pub fn clear(&self)

Clears all elements in the channel.

pub fn len(&self) -> usize

Returns the number of elements currently in the channel.

pub fn is_empty(&self) -> bool

Returns whether the channel is empty.

pub fn is_full(&self) -> bool

Returns whether the channel is full.

type Target = ImmediatePub<'a, PubSubChannel<M, T, CAP, SUBS, PUBS>, T>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
