Struct Signal 

pub struct Signal { /* private fields */ }

The deliveries of one signal, as a stream: each item stands for one delivery or more since the item before.

Implementations

impl Signal

pub async fn recv(&mut self) -> Option<()>

Waits for the next delivery. Always Some: the stream never ends.

pub fn poll_recv(&mut self, cx: &mut Context<'_>) -> Poll<Option<()>>

Ready with Some once the signal was delivered since the last item.

Trait Implementations

impl Debug for Signal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Stream for Signal

type Item = ()

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Option<()>>

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.
