Enum SendTimeoutError

pub enum SendTimeoutError<T> {
    Timeout(T),
    Disconnected(T),
}
Expand description

An error that may be emitted when sending a value into a channel on a sender with a timeout when the send operation times out or all receivers are dropped.

Variants§

§

Timeout(T)

A timeout occurred when attempting to send the message.

§

Disconnected(T)

All channel receivers were dropped and so the message has nobody to receive it.

Implementations§

§

impl<T> SendTimeoutError<T>

pub fn into_inner(self) -> T

Consume the error, yielding the message that failed to send.
