Struct SendStream 

pub struct SendStream { /* private fields */ }

An outgoing stream, WebTransport-framed when its session is.

finish can leave the WebTransport header owed, when the connection has no flow-control credit for it. The FIN then goes out on a later poll_closed, or on Drop if credit has returned by then. Dropping immediately after finishing, with no poll in between, leaves no moment for it to return and cancels the stream instead, so pair the two when a clean end matters.

Trait Implementations

impl Debug for SendStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SendStream

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl SendStream for SendStream

type Error = Error

The error type for every operation on this stream.

fn poll_write( &mut self, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Self::Error>>

Poll to write some of the buffer to the stream, returning how many bytes were written. See poll_write_buf for the partial-write contract, which this shares.

fn poll_write_buf<B: Buf>( &mut self, cx: &mut Context<'_>, buf: &mut B, ) -> Poll<Result<usize, Self::Error>>

Poll to write some of the given buffer to the stream, advancing it by the number of bytes written. This may be less than the whole buffer, so callers loop.

fn set_priority(&mut self, order: u8)

Set the stream’s priority.

fn finish(&mut self) -> Result<(), Self::Error>

Mark the stream as finished, erroring on any future writes.

fn reset(&mut self, code: u32)

Immediately closes the stream and discards any remaining data.

fn poll_closed(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Poll until the stream is closed by either side.
