Function http_response_read_body

Source 
pub fn http_response_read_body(
    request_id: <PassAs<HttpRequestId, u16> as RIType>::Inner,
    buffer: <PassFatPointerAndReadWrite<&mut [u8]> as RIType>::Inner,
    deadline: <PassFatPointerAndDecode<Option<Timestamp>> as RIType>::Inner,
) -> <AllocateAndReturnByCodec<Result<u32, HttpError>> as RIType>::Inner
Expand description

Read a chunk of body response to given buffer.

Returns the number of bytes written or an error in case a deadline is reached or server closed the connection. If 0 is returned it means that the response has been fully consumed and the request_id is now invalid. NOTE: this implies that response headers must be read before draining the body. Passing None as a deadline blocks forever.
