Struct H2Transport 

pub struct H2Transport { /* private fields */ }

A single HTTP/2 stream’s transport handle.

Carries a backref to the shared H2Connection, the stream id, and the per-stream Arc<StreamState> used by the read and write sides. Normal HTTP/2 operation reads through ReceivedBody and writes through the driver’s send queue; the AsyncRead / AsyncWrite impls here are only reached by code that borrows the transport directly (typically an upgrade handler after extended CONNECT).

Implementations

impl H2Transport

pub fn stream_id(&self) -> u32

The stream identifier this transport is bound to.

pub fn connection(&self) -> &Arc<H2Connection>

The shared H2Connection backing this stream.

Trait Implementations

impl AsyncRead for H2Transport

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, out: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl AsyncWrite for H2Transport

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

impl Debug for H2Transport

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

Formats the value using the given formatter.

impl Drop for H2Transport

fn drop(&mut self)

Application-side release / cancel signal, decided from the stream’s protocol state plus whether a response has been handed off:

• Already removed from the shared map — the driver beat us to cleanup; no-op.
• Closed (both halves done on the wire; client-role streams linger in the map for post-EOF trailer/response access) — set SendState::transport_dropped so the driver GCs the lingering entry.
• Send half still open + a response was submitted (submit_resolved) — a bidirectional upgrade tunnel the handler is dropping; enqueue OutboundPart::Close for a graceful END_STREAM.
• Anything else (HalfClosedLocal awaiting the peer, or send-open with no response ever submitted) — abandoning the stream; enqueue RST_STREAM(Cancel).

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.
