Struct sp_std::sync::mpsc::SendError

1.0.0 · source · [−]

pub struct SendError<T>(pub T);

Expand description

An error returned from the Sender::send or SyncSender::send function on channels.

A send operation can only fail if the receiving end of a channel is disconnected, implying that the data could never be received. The error contains the data being sent as a payload so it can be recovered.

impl<T> From<SendError<T>> for TrySendError<T>

source

pub fn from(err: SendError<T>) -> TrySendError<T>

Converts a SendError<T> into a TrySendError<T>.

This conversion always returns a TrySendError::Disconnected containing the data in the SendError<T>.

No data is allocated on the heap.
