Struct std::sync::mpsc::Sender
[−]
[src]
pub struct Sender<T> { // some fields omitted }
The sending-half of Rust's asynchronous channel type. This half can only be owned by one thread, but it can be cloned to send to other threads.
Methods
impl<T> Sender<T>
fn send(&self, t: T) -> Result<(), SendError<T>>
Attempts to send a value on this channel, returning it back if it could not be sent.
A successful send occurs when it is determined that the other end of
the channel has not hung up already. An unsuccessful send would be one
where the corresponding receiver has already been deallocated. Note
that a return value of Err
`Errmeans that the data will never be received, but a return value of
Okdoes *not* mean that the data will be received. It is possible for the corresponding receiver to hang up immediately after this function returns
Ok`.
This method will never block the current thread.
Examples
fn main() { use std::sync::mpsc::channel; let (tx, rx) = channel(); // This send is always successful tx.send(1).unwrap(); // This send will fail because the receiver is gone drop(rx); assert_eq!(tx.send(1).err().unwrap().0, 1); }use std::sync::mpsc::channel; let (tx, rx) = channel(); // This send is always successful tx.send(1).unwrap(); // This send will fail because the receiver is gone drop(rx); assert_eq!(tx.send(1).err().unwrap().0, 1);
