# Library shared byte-for-byte between the relay server and the mobile-connector
# plugin. Keep it lightweight: NO axum / tokio here. The `gen-vectors` binary
# (src/bin/gen-vectors.rs) reproduces the crypto interop vectors
# (data/ios-app/test-vectors.md §3) using only the library functions below.

# MsgPack wire format for the pipe control/data-plane messages (docs/relay/pipe.md).
# `rmp-serde` keeps the same serde derives as the JSON path so a struct maps to
# either format; the pipe layer is binary-first per the transport direction.
