Struct Rx 

pub struct Rx<F: Flavor> { /* private fields */ }

A single consumer (receiver) that works in a blocking context.

Additional methods in ChannelShared can be accessed through Deref.

NOTE: Rx is not Clone or Sync. If you need concurrent access, use MRx instead.

Rx has a Send marker and can be moved to other threads. The following code is OK:

use crossfire::*;
let (tx, rx) = mpsc::bounded_blocking::<usize>(100);
std::thread::spawn(move || {
    let _ = rx.recv();
});
drop(tx);

Because Rx does not have a Sync marker, using Arc<Rx> will lose the Send marker.

For your safety, the following code should not compile:

use crossfire::*;
use std::sync::Arc;
let (tx, rx) = mpsc::bounded_blocking(100);
let rx = Arc::new(rx);
std::thread::spawn(move || {
    let _ = rx.recv();
});
drop(tx);

Implementations

impl<F: Flavor> Rx<F>

pub fn recv<'a>(&'a self) -> Result<F::Item, RecvError>

Receives a message from the channel. This method will block until a message is received or the channel is closed.

Returns Ok(T) on success.

Returns Err(RecvError) if the sender has been dropped.

pub fn try_recv(&self) -> Result<F::Item, TryRecvError>

Attempts to receive a message from the channel without blocking.

Returns Ok(T) when successful.

Returns Err(TryRecvError::Empty) if the channel is empty.

Returns Err(TryRecvError::Disconnected) if the sender has been dropped and the channel is empty.

pub fn recv_timeout( &self, timeout: Duration, ) -> Result<F::Item, RecvTimeoutError>

Receives a message from the channel with a timeout. Will block when channel is empty.

The behavior is atomic: the message is either received successfully or the operation is canceled due to a timeout.

Returns Ok(T) when successful.

Returns Err(RecvTimeoutError::Timeout) when a message could not be received because the channel is empty and the operation timed out.

Returns Err(RecvTimeoutError::Disconnected) if the sender has been dropped and the channel is empty.

pub fn is_disconnected(&self) -> bool

Return true if the other side has closed

pub fn read_select(&self, result: SelectResult) -> Result<F::Item, RecvError>

where F: FlavorSelect,

This method use with select, guarantee non-blocking

Panics

Panics if SelectResult from other receiver is passed.

pub fn into_async(self) -> AsyncRx<F>

Methods from Deref<Target = ChannelShared<F>>

pub fn len(&self) -> usize

The number of messages in the channel.

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

The capacity of the channel. Returns None for unbounded channels.

pub fn is_empty(&self) -> bool

Returns true if the channel is empty.

pub fn is_full(&self) -> bool

Returns true if the channel is full.

pub fn get_tx_count(&self) -> usize

Returns the number of senders for the channel.

pub fn get_rx_count(&self) -> usize

Returns the number of receivers for the channel.

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

Returns the number of wakers for senders and receivers. For debugging purposes.
