An extension trait for HTTP Responses.

This is used to send a response back downstream to a client that made a request.

Required methods

fn inner_to_body(self) -> Response<Body>

Replace the body of a response with a Body with the same contents.

fn inner_to_bytes(self) -> Response<Vec<u8>>

Replace the body of a response with the remaining contents of its body.

Note that this will involve copying and buffering the body, and so should only be used for convenience on small response bodies.

fn fastly_metadata(&self) -> Option<&FastlyResponseMetadata>

Get a reference to the Fastly-specific metadata associated with this response.

This method will return None if this response did not come from an origin server.

fn fastly_metadata_mut(&mut self) -> Option<&mut FastlyResponseMetadata>

Get a mutable reference to the Fastly-specific metadata associated with this response.

This method will return None if this response did not come from an origin server.

Provided methods

fn send_downstream(self)

Send a response downstream to the client.

fn send_downstream_streaming(self) -> StreamingBodyⓘ

Notable traits for StreamingBody

impl Write for StreamingBody

Begin streaming a response downstream, returning a StreamingBody that can be appended.

fn backend(&self) -> Option<&Backend>

Get the Backend that this response came from, if this response came from a backend request.

fn backend_request(&self) -> Option<&Request<()>>

Get the request that this response came from, if this response came from a backend request.

This method will return None if this response did not come from a backend, or the request has been taken by backend_request_take().

Since the original request's body is consumed by sending it, the body in this request is empty (represented by ()).

fn take_backend_request(&mut self) -> Option<Request<()>>

Take the request that this response came from, if this response came from a backend request.

This method will return None if this response did not come from a backend, or if the request has been previously taken.

In contrast to RequestExt::backend_request(), this returns an owned Request<()>, which can be used to send another request to a backend.

Since the original request's body is consumed by sending it, the body in this request is empty (represented by ()). To add a new body to the request, use Request::map(), for example:

let new_body = Body::from("something new");
let new_req = beresp.take_backend_request().unwrap().map(|()| new_body);
new_req.send("my_backend")
