Struct DataReader
pub struct DataReader {
state: Option<DataReaderState>,
_memquota: StreamAccount,
ctrl: Arc<ClientDataStreamCtrl>,
}
Expand description
The read half of a DataStream
, implementing [futures::io::AsyncRead
].
See the DataStream
docs for more information.
§Usage with Tokio
If the tokio
crate feature is enabled, this type also implements
tokio::io::AsyncRead
for easier integration
with code that expects that trait.
Fields§
§state: Option<DataReaderState>
§_memquota: StreamAccount
§ctrl: Arc<ClientDataStreamCtrl>
Available on crate feature
stream-ctrl
only.Implementations§
§impl DataReader
impl DataReader
pub fn client_stream_ctrl(&self) -> Option<&Arc<ClientDataStreamCtrl>>
Available on crate feature stream-ctrl
only.
pub fn client_stream_ctrl(&self) -> Option<&Arc<ClientDataStreamCtrl>>
stream-ctrl
only.Return a [ClientDataStreamCtrl
] object that can be used to monitor and
interact with this stream without holding the stream itself.
