Struct h2::server::SendPushedResponse
source · [−]pub struct SendPushedResponse<B: Buf> { /* private fields */ }Expand description
Send a response to a promised request
A SendPushedResponse instance is provided when promising a request and is used
to send the associated response to the client. It is also used to
explicitly reset the stream with a custom reason.
It can not be used to initiate push promises.
If the SendPushedResponse instance is dropped without sending a response, then
the HTTP/2 stream will be reset.
See module level docs for more details.
Implementations
sourceimpl<B: Buf> SendPushedResponse<B>
impl<B: Buf> SendPushedResponse<B>
sourcepub fn send_response(
&mut self,
response: Response<()>,
end_of_stream: bool
) -> Result<SendStream<B>, Error>
pub fn send_response(
&mut self,
response: Response<()>,
end_of_stream: bool
) -> Result<SendStream<B>, Error>
Send a response to a promised request.
On success, a SendStream instance is returned. This instance can be
used to stream the response body and send trailers.
If a body or trailers will be sent on the returned SendStream
instance, then end_of_stream must be set to false when calling this
function.
The SendPushedResponse instance is associated with a promised
request. This function may only be called once per instance and only if
send_reset has not been previously called.
sourcepub fn send_reset(&mut self, reason: Reason)
pub fn send_reset(&mut self, reason: Reason)
Send a stream reset to the peer.
This essentially cancels the stream, including any inbound or outbound data streams.
If this function is called before send_response, a call to
send_response will result in an error.
If this function is called while a SendStream instance is active,
any further use of the instance will result in an error.
This function should only be called once.
sourcepub fn poll_reset(&mut self, cx: &mut Context<'_>) -> Poll<Result<Reason, Error>>
pub fn poll_reset(&mut self, cx: &mut Context<'_>) -> Poll<Result<Reason, Error>>
Polls to be notified when the client resets this stream.
If stream is still open, this returns Poll::Pending, and
registers the task to be notified if a RST_STREAM is received.
If a RST_STREAM frame is received for this stream, calling this
method will yield the Reason for the reset.
Error
Calling this method after having called send_response will return
a user error.
