Struct wtransport :: stream :: SendStream Copy item path

impl SendStream

pub async fn write(&mut self, buf: &[u8]) -> Result<usize, StreamWriteError>

Writes bytes to the stream.

On success, returns the number of bytes written. Congestion and flow control may cause this to be shorter than buf.len(), indicating that only a prefix of buf was written.

pub async fn write_all(&mut self, buf: &[u8]) -> Result<(), StreamWriteError>

Convenience method to write an entire buffer to the stream.

pub async fn finish(&mut self) -> Result<(), StreamWriteError>

Shut down the stream gracefully.

No new data may be written after calling this method. Completes when the peer has acknowledged all sent data, retransmitting data as needed.

pub fn id(&self) -> StreamId

Returns the StreamId associated.

pub fn set_priority(&self, priority: i32)

Sets the priority of the send stream.

Every send stream has an initial priority of 0. Locally buffered data from streams with higher priority will be transmitted before data from streams with lower priority. Changing the priority of a stream with pending data may only take effect after that data has been transmitted. Using many different priority levels per connection may have a negative impact on performance.

pub fn priority(&self) -> i32

Gets the priority of the send stream.

pub fn reset(self, error_code: VarInt)

Closes the send stream immediately.

No new data can be written after calling this method. Locally buffered data is dropped, and previously transmitted data will no longer be retransmitted if lost. If an attempt has already been made to finish the stream, the peer may still receive all written data.

pub async fn stopped(self) -> StreamWriteError

Awaits for the stream to be stopped by the peer.

If the stream is stopped the error code will be stored in StreamWriteError::Stopped.

pub fn quic_stream(&self) -> &SendStream

Available on crate feature quinn only.

Returns a reference to the underlying QUIC stream.

pub fn quic_stream_mut(&mut self) -> &mut SendStream

Available on crate feature quinn only.

Returns a mutable reference to the underlying QUIC stream.
