[−][src]Struct abi_stable::external_types::crossbeam_channel::RSender
The sender end of a channel, which can be either bounded or unbounded.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<&'static str>(1024); std::thread::spawn(move||{ for _ in 0..4{ tx.send("Are we there yet.").unwrap(); } }); assert_eq!(rx.recv().unwrap(),"Are we there yet."); assert_eq!(rx.recv().unwrap(),"Are we there yet."); assert_eq!(rx.recv().unwrap(),"Are we there yet."); assert_eq!(rx.recv().unwrap(),"Are we there yet."); assert!( rx.recv().is_err() );
Methods
impl<T> RSender<T>
[src]
pub fn send(&self, value: T) -> Result<(), SendError<T>>
[src]
Blocks until value
is either sent,or the the other end is disconnected.
If the channel queue is full,this will block to send value
.
If the channel is disconnected,this will return an error with value
.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<u32>(3); tx.send(1057).unwrap(); drop(rx); assert!( tx.send(0).is_err() );
pub fn try_send(&self, value: T) -> Result<(), TrySendError<T>>
[src]
Immediately sends value
,or returns with an error.
An error will be returned in these 2 conditions:
-
the channel is full.
-
the channel has been disconnected.
If the channel has a capacity of 0,it will only send value
if
the other end is calling recv
.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<bool>(1); tx.try_send(true).unwrap(); assert!( tx.try_send(true).unwrap_err().is_full() ); drop(rx); assert!( tx.try_send(false).unwrap_err().is_disconnected() );
pub fn send_timeout(
&self,
value: T,
timeout: Duration
) -> Result<(), SendTimeoutError<T>>
[src]
&self,
value: T,
timeout: Duration
) -> Result<(), SendTimeoutError<T>>
Blocks until a timeout to send value
.
An error will be returned in these 2 conditions:
-
the value could not be sent before the timeout.
-
the channel has been disconnected.
If the channel has a capacity of 0,it will only send value
if
the other end calls recv
before the timeout.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; use std::time::Duration; let (tx,rx)=mpmc::bounded::<()>(1); let timeout=Duration::from_millis(1); tx.send_timeout((),timeout).unwrap(); assert!( tx.send_timeout((),timeout).unwrap_err().is_timeout() ); drop(rx); assert!( tx.send_timeout((),timeout).unwrap_err().is_disconnected() );
pub fn is_empty(&self) -> bool
[src]
Returns true if there are no values in the channel queue.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<()>(1); assert!( tx.is_empty() ); tx.send(()).unwrap(); assert!( !tx.is_empty() ); rx.recv().unwrap(); assert!( tx.is_empty() );
pub fn is_full(&self) -> bool
[src]
Returns true if the channel queue is full.
This always returns true for channels constructed with bounded(0)
.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<()>(2); assert!( !tx.is_full() ); tx.send(()).unwrap(); assert!( !tx.is_full() ); tx.send(()).unwrap(); assert!( tx.is_full() ); rx.recv().unwrap(); assert!( !tx.is_full() );
pub fn len(&self) -> usize
[src]
Returns the ammount of values in the channel queue.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; let (tx,rx)=mpmc::bounded::<()>(2); assert_eq!(tx.len(),0); tx.send(()).unwrap(); assert_eq!(tx.len(),1); tx.send(()).unwrap(); assert_eq!(tx.len(),2); rx.recv().unwrap(); assert_eq!(tx.len(),1);
pub fn capacity(&self) -> Option<usize>
[src]
Returns the ammount of values the channel queue can hold.
This returns None if the channel is unbounded.
Example
use abi_stable::external_types::crossbeam_channel as mpmc; { let (tx,rx)=mpmc::bounded::<()>(2); assert_eq!(tx.capacity(),Some(2)); } { let (tx,rx)=mpmc::unbounded::<()>(); assert_eq!(tx.capacity(),None); }
