data.drivers._pelt._codecs_uuid_bytea

E2 codec family:uuid and bytea.

Two leaf codecs that round-trip Pythonuuid.UUID and bytesagainst the PostgreSQL binary + text wire formats. Both are non-parametric (a fixed OID, no element/typmod), so they ship inLEAF_CODECSready for the registry — the long-tail temporal/numeric and the parametric array/composite families land in sibling E2 modules built on the same Codecshape.

Wire layouts (cf.pg_type.dat + src/backend/utils/adt/uuid.c / varlena.c):

• uuid(OID 2950): binary is the 16 raw UUID bytes, big-endian (network) order — the same byte order asbytes. Text is the canonical 8-4-4-4-12 hyphenated hex.
• bytea(OID 17): binary is the raw octet string, a verbatim passthrough. Text is the PostgreSQL hex format — the literal prefix\xfollowed by lowercase hex (the default bytea_output); the legacy escapeformat is not emitted and not decoded here.

Faults raise pelt'sProtocolError (a PELT_* code), never a bare exception — a malformed-lengthuuid or an unknown byteatext prefix is a backend/stream defect, not programmer misuse. Live-PG parity deferred to E4/E6 integration.
