Struct embassy_sync::pubsub::publisher::ImmediatePub

pub struct ImmediatePub<'a, PSB: PubSubBehavior<T> + ?Sized, T: Clone> { /* private fields */ }

A publisher that can only use the publish_immediate function, but it doesn’t have to be registered with the channel. (So an infinite amount is possible)

Implementations

impl<'a, PSB: PubSubBehavior<T> + ?Sized, T: Clone> ImmediatePub<'a, PSB, 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 space(&self) -> usize

The amount of messages that can still be published without having to wait or without having to lag the subscribers

Note: In the time between checking this and a publish action, other publishers may have had time to publish something. So checking doesn’t give any guarantees.
