Required Methods

fn send_informational( &mut self, self_: Resource<ResponseOutparam>, status: u16, headers: Resource<Headers>, ) -> Result<(), HttpError>

Send an HTTP 1xx response.

Unlike response-outparam.set, this does not consume the response-outparam, allowing the guest to send an arbitrary number of informational responses before sending the final response using response-outparam.set.

This will return an HTTP-protocol-error if status is not in the range [100-199], or an internal-error if the implementation does not support informational responses.

fn set( &mut self, param: Resource<ResponseOutparam>, response: Result<Resource<OutgoingResponse>, ErrorCode>, ) -> Result<()>

Set the value of the response-outparam to either send a response, or indicate an error.

This method consumes the response-outparam to ensure that it is called at most once. If it is never called, the implementation will respond with an error.

The user may provide an error to response to allow the implementation determine how to respond with an HTTP error response.

fn drop(&mut self, rep: Resource<ResponseOutparam>) -> Result<()>
