pub struct StreamManagerHandle { /* private fields */ }Expand description
A StreamManagerHandle supports operations for interacting with the StreamManager.
Streams can be registered for reading, returning a StreamReader, or for writing, returning
a StreamWriter.
Implementations§
Source§impl StreamManagerHandle
impl StreamManagerHandle
Sourcepub fn read_stream<T, W>(
&self,
id: StreamId,
writer: W,
) -> Result<StreamReader<T, W>, ShellError>
pub fn read_stream<T, W>( &self, id: StreamId, writer: W, ) -> Result<StreamReader<T, W>, ShellError>
Register a new stream for reading, and return a StreamReader that can be used to iterate
on the values received. A StreamMessage writer is required for writing control messages
back to the producer.
Sourcepub fn write_stream<W>(
&self,
id: StreamId,
writer: W,
high_pressure_mark: i32,
) -> Result<StreamWriter<W>, ShellError>where
W: WriteStreamMessage,
pub fn write_stream<W>(
&self,
id: StreamId,
writer: W,
high_pressure_mark: i32,
) -> Result<StreamWriter<W>, ShellError>where
W: WriteStreamMessage,
Register a new stream for writing, and return a StreamWriter that can be used to send
data to the stream.
The high_pressure_mark value controls how many messages can be written without receiving
an acknowledgement before any further attempts to write will wait for the consumer to
acknowledge them. This prevents overwhelming the reader.
