Struct embassy_sync::pubsub::publisher::ImmediatePublisher

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

An immediate publisher that holds a generic reference to the channel

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

source

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.

source

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

Publish a message if there is space in the message queue

source

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.
