# Struct bitflags::__core::sync::mpsc::Sender [−] [src]

    pub struct Sender<T> {
        // some fields omitted
    }

1.0.0

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` means that the data will never be received, but a return value of `Ok` does 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

    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);

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
