Implementations§
Source§impl<T> Receiver<T>
impl<T> Receiver<T>
Sourcepub fn recv(&self) -> Result<T, RecvError>
pub fn recv(&self) -> Result<T, RecvError>
Blocks the current thread until a message is received or the channel is disconnected.
§Blocking
- If no message is ready and at least one Sender still
exists, execution is suspended until either
- a message is sent, or
- every Sender is dropped.
§Buffered
- Messages sent before the last Sender is dropped are still delivered.
§Errors
Once all senders are gone, and all buffered messages are consumed,
all subsequent calls return RecvError
.
§Safety
Channels are prone to deadlocks. You shall ensure a message will be sent via a corresponding Sender, or that all corresponding Senders will be dropped.
§Examples
use ps_mpmc::channel;
let (tx, rx) = channel::<i32>().into_parts();
std::thread::spawn(move || { tx.send(42).unwrap(); });
assert_eq!(rx.recv(), Ok(42));
assert_eq!(rx.recv(), Err(std::sync::mpsc::RecvError));
See also std::sync::mpsc::Receiver::recv
for details of the underlying implementation.
