Struct ResponseWriter 

pub struct ResponseWriter<W> { /* private fields */ }

The response lane. A partially sent or abandoned response permanently poisons admission. The owner must still await close to retire the backend.

Implementations

impl<W: WritableStream> ResponseWriter<W>

pub fn new(writer: W) -> Self

pub fn is_usable(&self) -> bool

Whether another message can be written. A failed write which leaves output usable wrote none of its message, so the owner can still send a different response.

pub fn interim(&mut self, version: Version) -> InterimWriter<'_, W>

pub async fn reject( &mut self, status: Status, cancellation: &Cancellation, ) -> Result<(), Error>

Best-effort rejection for invalid input, followed by connection closure.

pub async fn write_response<B: ReadableBody>( &mut self, exchange: &Exchange, response: &mut Response<B>, cancellation: &Cancellation, ) -> Result<bool, Error>

Write one final response. true means output permits persistence; the connection owner must also finish input and join concurrent work before admitting another request. Discarded input disables persistence.

A response refused before any of it is written, such as one with an informational status, conflicting framing or a Content-Length field its body contradicts, leaves output usable.

A response to an HTTP/1.0 request has no chunked framing, so any trailers its body produces are dropped.

pub async fn close(&mut self) -> Result<()>
