pub struct PubSub<T> { /* private fields */ }
Expand description
A pub-sub queue.
Implementations
sourceimpl<T> PubSub<T>
impl<T> PubSub<T>
sourcepub fn subscribe(&mut self) -> Subscription<T>
pub fn subscribe(&mut self) -> Subscription<T>
Subscribe to the queue.
A subscription cannot be cancelled.
sourcepub fn read_ith(&self, sub: &Subscription<T>, i: usize) -> Option<&T>
pub fn read_ith(&self, sub: &Subscription<T>, i: usize) -> Option<&T>
Read the i-th message not yet read by the given subsciber.
sourcepub fn read(&self, sub: &Subscription<T>) -> impl Iterator<Item = &T>
pub fn read(&self, sub: &Subscription<T>) -> impl Iterator<Item = &T>
Get the messages not yet read by the given subscriber.
sourcepub fn ack(&mut self, sub: &Subscription<T>)
pub fn ack(&mut self, sub: &Subscription<T>)
Makes the given subscribe acknowledge all the messages in the queue.
A subscriber cannot read acknowledged messages any more.

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
sourcefn is_in_subset(&self) -> bool

fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
sourcefn from_subset(element: &SS) -> SP

The inclusion map: converts self
to the equivalent element of its superset.
