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

A subscriber that holds a generic reference to the channel

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

source

pub fn next_message<'s>(&'s mut self) -> SubscriberWaitFuture<'s, 'a, PSB, T>

Wait for a published message

source

pub async fn next_message_pure(&mut self) -> T

Wait for a published message (ignoring lag results)

source

pub fn try_next_message(&mut self) -> Option<WaitResult<T>>

Try to see if there’s a published message we haven’t received yet.

This function does not peek. The message is received if there is one.

source

pub fn try_next_message_pure(&mut self) -> Option<T>

Try to see if there’s a published message we haven’t received yet (ignoring lag results).

This function does not peek. The message is received if there is one.

source

pub fn available(&self) -> u64

The amount of messages this subscriber hasn’t received yet
