pub fn serialize_request(req: &HttpRequest) -> Vec<u8> ⓘExpand description
Serialize a request to bytes: request line (method, percent-encoded path and
query, HTTP/1.1), the request’s headers (minus the writer-owned framing
ones), an accurate Content-Length, Connection: close, the blank line,
then the body — the exact client-side mirror of serialize_response.
Host rides in headers like any other header (HttpRequest has no
separate host field): callers building a client request put host in the
map and the writer emits it verbatim — it never synthesizes one. path and
query are the decoded forms (parse_request’s output); the writer
percent-encodes them (RFC 3986 unreserved set, / kept literal in the
path), so parse_request(&serialize_request(req)) reconstructs them
exactly.
