Struct MAsyncTx

pub struct MAsyncTx<T>(/* private fields */);

Multi-producer (sender) that works in async context.

Inherits AsyncTx<T> and implements Clone. Additional methods can be accessed through Deref<Target=ChannelShared>.

You can use into() to convert it to AsyncTx<T>.

MAsyncTx can be converted into MTx via From trait, that means you can have two types of senders both within async and blocking context to the same channel.

Implementations

impl<T> MAsyncTx<T>

pub fn into_sink(self) -> AsyncSink<T>

pub fn into_blocking(self) -> MTx<T>

Methods from Deref<Target = AsyncTx<T>>

pub fn try_send(&self, item: T) -> Result<(), TrySendError<T>>

Try to send message, non-blocking

Returns Ok(()) when successful.

Returns Err(TrySendError::Full) on channel full for bounded channel.

Returns Err(TrySendError::Disconnected) when all Rx dropped.

pub fn len(&self) -> usize

The number of messages in the channel at the moment

pub fn capacity(&self) -> Option<usize>

The capacity of the channel

pub fn is_empty(&self) -> bool

Whether channel is empty at the moment

pub fn is_full(&self) -> bool

Whether the channel is full at the moment

pub fn send<'a>(&'a self, item: T) -> SendFuture<'a, T>

Send message. Will await when channel is full.

Returns Ok(()) on successful.

Returns Err(SendError) when all Rx is dropped.

pub fn make_send_future<'a>(&'a self, item: T) -> SendFuture<'a, T>

👎Deprecated

Use send() instead

pub fn send_timeout<'a>( &'a self, item: T, duration: Duration, ) -> SendTimeoutFuture<'a, T>

Available on crate features tokio or async_std only.

Waits for a message to be sent into the channel, but only for a limited time. Will await when channel is full.

The behavior is atomic, either message sent successfully or returned on error.

Returns Ok(()) when successful.

Returns Err(SendTimeoutError::Timeout) when the operation timed out.

Returns Err(SendTimeoutError::Disconnected) when all Rx dropped.

pub fn send_blocking(&self, item: T) -> Result<(), SendError<T>>

Send a message while blocking the current thread. Be careful!

Returns Ok(())on successful.

Returns Err(SendError) when all Rx is dropped.

NOTE: Do not use it in async context otherwise will block the runtime.

Methods from Deref<Target = ChannelShared>

pub fn is_disconnected(&self) -> bool

Return true if all the senders or receivers are dropped

pub fn get_tx_count(&self) -> usize

Get the count of alive senders

pub fn get_rx_count(&self) -> usize

Get the count of alive receivers

pub fn get_wakers_count(&self) -> (usize, usize)

Just for debugging purpose, to monitor queue size
