pub struct PubSub<T> { /* fields omitted */ }
Expand description
A pub-sub queue.
Implementations
impl<T> PubSub<T>
impl<T> PubSub<T>
pub fn publish(&mut self, message: T)
pub fn publish(&mut self, message: T)
Publish a new message.
pub fn subscribe(&mut self) -> Subscription<T>
pub fn subscribe(&mut self) -> Subscription<T>
Subscribe to the queue.
A subscription cannot be cancelled.
pub 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.
pub 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.
pub 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
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
