Module codec 

Codec module - serialization/deserialization for payloads.

This module provides codecs for encoding/decoding frame payloads:

• RawCodec - Pass-through for raw bytes (zero-copy)
• MsgPackCodec - MessagePack using rmp-serde (to_vec_named for Node.js compatibility)

Design

Codecs are implemented as marker structs with static methods rather than trait objects. This allows for compile-time codec selection and enables zero-copy optimizations.

Example

use procwire_client::codec::{MsgPackCodec, RawCodec};
use bytes::Bytes;

// MsgPack codec for structured data
let encoded = MsgPackCodec::encode(&"hello").unwrap();
let decoded: String = MsgPackCodec::decode(&encoded).unwrap();
assert_eq!(decoded, "hello");

// Raw codec for binary data
let raw = RawCodec::serialize(b"binary data");
assert_eq!(RawCodec::deserialize(&raw), b"binary data");

Structs

MsgPackCodec

MessagePack codec for structured data.

RawCodec

Raw codec that passes bytes through without transformation.
