Module codec 

Available on crate feature transport only.

Parse-on-demand codec

The spine frames bytes into a WorkBatch WITHOUT parsing. A transform/router that needs a field parses on demand here, format- agnostic.

Native, no JSON bridge

No rmp_serde -> serde_json::Value -> sonic_rs double-parse anywhere on the parse path. Both arms decode natively:

• JSON – sonic_rs (SIMD, AVX2/NEON).
• MsgPack – rmpv schema-less Value decoder. No intermediate serde_json::Value, no JSON re-serialise.

Unified routing-field accessor

A router keys off ONE field and must not branch on wire format. ParsedPayload exposes a format-agnostic accessor:

• ParsedPayload::field_str – the common case: a top-level string field.
• ParsedPayload::field – a FieldRef over the scalar routing cases (string/int/float/bool/null); everything else collapses to FieldRef::Other because routers do not key off containers.

Scope: top-level object-key lookup only. No deep JSON-path (YAGNI – keys live at the top level).

See docs/MIGRATIONS.md and docs/SELF-REGULATION.md. Block contract in WorkBatch.

Enums

CodecError

A parse failure, tagged by the format that failed.

FieldRef

A borrowed view of one routing field, format-agnostic.

ParsedPayload

A parsed payload, retaining its native value representation.

Functions

parse

Parse a framed payload into a native ParsedPayload.

to_json_bytes

Serialise a JSON value to bytes via sonic_rs (SIMD), no bridge.

to_msgpack_bytes

Serialise a MsgPack value to bytes via NATIVE rmpv::encode::write_value.
