Struct Subscription 

pub struct Subscription<T: RoutableEvent> { /* private fields */ }

A live subscription to one target: a Stream of the events routed there. Dropping it unsubscribes (and drops the target if it was the last one).

Trait Implementations

impl<T: RoutableEvent> Drop for Subscription<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T: RoutableEvent> Stream for Subscription<T>

where T::Target: Unpin,

type Item = T

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Option<T>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
