Length-Prefixed Private Frame Codec (daemon/framing.rs)

A Rust wire codec using an 8-bit length prefix for framing JSON headers and binary payloads over worker sockets. Reuse when building high-performance IPC or daemon client protocols.

//! Length-prefixed private frames: the worker-socket wire codec shared by pa-daemon workers and

//! header length, u32 payload length), JSON header, binary payload.
