Struct holochain::prelude::kitsune_p2p::dependencies::kitsune_p2p_types::dependencies::futures::channel::oneshot::Cancellation
pub struct Cancellation<'a, T> { /* private fields */ }
Expand description
A future that resolves when the receiving end of a channel has hung up.
This is an .await
-friendly interface around poll_canceled
.
