Methods from Deref<Target = Pub<'a, PubSubChannel<M, T, CAP, SUBS, PUBS>, T>>§
sourcepub fn publish_immediate(&self, message: T)
pub fn publish_immediate(&self, message: T)
Publish a message right now even when the queue is full. This may cause a subscriber to miss an older message.
sourcepub fn publish<'s>(&'s self, message: T) -> PublisherWaitFuture<'s, 'a, PSB, T> ⓘ
pub fn publish<'s>(&'s self, message: T) -> PublisherWaitFuture<'s, 'a, PSB, T> ⓘ
Publish a message. But if the message queue is full, wait for all subscribers to have read the last message
sourcepub fn try_publish(&self, message: T) -> Result<(), T>
pub fn try_publish(&self, message: T) -> Result<(), T>
Publish a message if there is space in the message queue
sourcepub fn free_capacity(&self) -> usize
pub fn free_capacity(&self) -> usize
Returns the free capacity of the channel.
This is equivalent to capacity() - len()
