Struct holochain::prelude::dependencies::kitsune_p2p_types::dependencies::lair_keystore_api::dependencies::tokio::io::Empty
source · pub struct Empty { /* private fields */ }
Expand description
An async reader which is always at EOF.
This struct is generally created by calling empty
. Please see
the documentation of empty()
for more details.
This is an asynchronous version of std::io::empty
.
