Module request 

RNS 1.4.2 Link.request (context 0x09) and its answer (0x0A).

• A request is msgpack [time, truncated_hash(path), data].
• The response is msgpack [request_id, data]. data crosses as raw msgpack value bytes.

Payloads past the link MDU are Resource territory, refused here.

Structs

ParsedRequest

RequestId

RNS 1.4.2 packet.getTruncatedHash(), naming the request in its response.

RespondDispatch

SendRequestDispatch

Enums

LinkRequestWriteError

PackBinaryError

RequestPlaintextError

ResponsePlaintextError

Constants

MAX_PACKED_BINARY_HEADER_LEN

REQUEST_RESPONSE_GRACE_MS

RNS 1.4.2 Resource.RESPONSE_MAX_GRACE_TIME (10 s) × 1.125, the flat term in a request’s default timeout: rtt × traffic_timeout_factor + 11.25 s.

REQUEST_WIRE_OVERHEAD

msgpack fixarray(3) ‖ float64 time ‖ bin8(16) path hash, before data.

RESPONSE_WIRE_OVERHEAD

msgpack fixarray(2) ‖ bin8(16) request id, before data.

WRAPPED_PLAINTEXT_CAP

Both verbs’ data caps derive from the single-packet link MDU, so the two sides land on the same figure by construction.

Functions

packed_binary_header_len

packed_binary_len

parse_request_plaintext

Hostile floats saturate the way the LRRTT parse does; anything not shaped like the reference’s three-element pack is refused.

parse_response_plaintext

response_data_wire_len

umsgpack.packb([request_id, response]). An empty response body still rides as one msgpack nil byte.

response_envelope_prefix

write_packed_binary_header

write_request_plaintext

write_response_plaintext
