Struct ssb_packetstream::PacketStream

pub struct PacketStream<R> { /* fields omitted */ }

Examples

use futures::executor::block_on;
use futures::sink::SinkExt;
use futures::stream::TryStreamExt;
use ssb_packetstream::*;

let p = Packet::new(IsStream::Yes,
                    IsEnd::No,
                    BodyType::Binary,
                    12345,
                    vec![1,2,3,4,5]);

let (writer, reader) = async_ringbuffer::ring_buffer(64);

let mut sink = PacketSink::new(writer);
let mut stream = PacketStream::new(reader);

    let r = stream.try_next().await.unwrap().unwrap();
    assert_eq!(&r.body, &[1,2,3,4,5]);

Trait Implementations

impl<R: AsyncRead + Unpin + 'static> Stream for PacketStream<R>

type Item = Result<Packet, Error>

Values yielded by the stream.

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

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.
