pub fn http_response_read_body(
    request_id: HttpRequestId,
    buffer: &mut [u8],
    deadline: Option<Timestamp>,
) -> Result<u32, HttpError>
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.
