Implementations

impl<T> Sender<T>

pub fn send(self, message: T) -> Result<(), SendError<T>>

Sends message over the channel to the corresponding Receiver.

Returns an error if the receiver has already been dropped. The message can be extracted from the error.

This method is lock-free and wait-free when sending on a channel that the receiver is currently not receiving on. If the receiver is receiving during the send operation this method includes waking up the thread/task. Unparking a thread involves a mutex in Rust’s standard library at the time of writing this. How lock-free waking up an async task is depends on your executor. If this method returns a SendError, please mind that dropping the error involves running any drop implementation on the message type, and freeing the channel’s heap allocation, which might or might not be lock-free.
