pub struct RequestWriter<W> { /* private fields */ }Expand description
Sequential client output. Drive this lane concurrently with ResponseReader
so an upstream response can arrive before request production completes.
No dialing, pooling, detached task or Expect/Continue wait policy is hidden.

pub fn new(writer: W) -> Self
Sourcepub fn is_reusable(&self) -> bool
pub fn is_reusable(&self) -> bool
Whether this output lane permits another request. This does not check completion of the independent response lane.
Sourcepub async fn write_request<B: ReadableBody>(
&mut self,
request: &mut Request<B>,
cancellation: &Cancellation,
) -> Result<bool, Error>
pub async fn write_request<B: ReadableBody>( &mut self, request: &mut Request<B>, cancellation: &Cancellation, ) -> Result<bool, Error>
Send one request. true permits another output message; the owner must
also finish the matching response before reusing the HTTP/1 connection.
The body is closed on return, including error and cancellation.
Sourcepub async fn begin_request(
&mut self,
metadata: &RequestMetadata,
cancellation: &Cancellation,
) -> Result<(), Error>
pub async fn begin_request( &mut self, metadata: &RequestMetadata, cancellation: &Cancellation, ) -> Result<(), Error>
Begin imperative output. A missing content length uses chunked HTTP/1.1 framing; declared fixed lengths are checked at every write and at EOF. After failure or cancellation this lane must be retired.
Sourcepub async fn write_frame<D: AsRef<[u8]>>(
&mut self,
frame: BodyFrame<D>,
cancellation: &Cancellation,
) -> Result<(), Error>
pub async fn write_frame<D: AsRef<[u8]>>( &mut self, frame: BodyFrame<D>, cancellation: &Cancellation, ) -> Result<(), Error>
Directly encode and flush one frame. Taking the encoder before awaiting makes a dropped, partially completed write permanently non-resumable.
Sourcepub async fn flush(&mut self, cancellation: &Cancellation) -> Result<(), Error>
pub async fn flush(&mut self, cancellation: &Cancellation) -> Result<(), Error>
Flush pending transport output. A failure retires the lane; accepted bytes must not be replayed after an interrupted flush.
