[−][src]Struct glommio::channels::local_channel::LocalSender
Send endpoint to the local_channel
Implementations
impl<T> LocalSender<T>
[src]
pub fn try_send(&self, item: T) -> Result<(), ChannelError<T>>
[src]
Sends data into this channel.
It returns a ChannelError
encapsulating a BrokenPipe
if the receiver is destroyed.
It returns a ChannelError
encapsulating a WouldBlock
if this is a bounded channel that has no more capacity
Examples
use glommio::{LocalExecutor, Local}; use glommio::channels::local_channel; use futures_lite::StreamExt; let ex = LocalExecutor::make_default(); ex.run(async move { let (sender, mut receiver) = local_channel::new_bounded(1); sender.try_send(0); sender.try_send(0).unwrap_err(); // no more capacity receiver.next().await.unwrap(); // now we have capacity again drop(receiver); // but because the receiver is destroyed send will err sender.try_send(0).unwrap_err(); });
pub async fn send<'_>(&'_ self, item: T) -> Result<(), ChannelError<T>>
[src]
Sends data into this channel when it is ready to receive it
For an unbounded channel this is just a more expensive version of send
. Prefer
to use send
instead.
For a bounded channel this will push to the channel when the channel is ready to receive data.
Examples
use glommio::{LocalExecutor, Local}; use glommio::channels::local_channel; let ex = LocalExecutor::make_default(); ex.run(async move { let (sender, receiver) = local_channel::new_bounded(1); sender.send(0).await.unwrap(); drop(receiver); });
pub fn is_full(&self) -> bool
[src]
Checks if there is room to send data in this channel
Examples
use glommio::{LocalExecutor, Local}; use glommio::channels::local_channel; let ex = LocalExecutor::make_default(); ex.run(async move { let (sender, receiver) = local_channel::new_bounded(1); assert_eq!(sender.is_full(), false); sender.try_send(0); assert_eq!(sender.is_full(), true); drop(receiver); });
pub fn len(&self) -> usize
[src]
Returns the number of items still queued in this channel
Examples
use glommio::{LocalExecutor, Local}; use glommio::channels::local_channel; use futures_lite::StreamExt; let ex = LocalExecutor::make_default(); ex.run(async move { let (sender, mut receiver) = local_channel::new_unbounded(); sender.try_send(0); sender.try_send(0); assert_eq!(sender.len(), 2); receiver.next().await.unwrap(); assert_eq!(sender.len(), 1); drop(receiver); });
