Module wal 

WAL segment envelopes, records, and codecs.

Structs

WalCommitDelta

Associates a materialized WAL delta with the semantic operation that produced it.

WalCommitPayload

Carries one accepted logical commit inside a WAL segment.

WalSegmentEnvelope

In-memory view of a WAL segment envelope.

WalSegmentPayload

Carries the namespace-specific chain metadata and commits stored in one WAL object.

Enums

WalDelta

Records one replayable metadata mutation materialized from a semantic commit operation.

WalEnvelopeKind

Identifies the durable payload family carried by a WAL envelope.

Constants

WAL_FORMAT_VERSION

Version 1: a zstd-compressed CBOR envelope document carrying the payload as an opaque CBOR byte string. payload_checksum covers exactly those bytes, and delta/precondition tags use the snake_case names the format spec fixes (“Standard mutation operations” and “Preconditions”).

Functions

decode_wal_segment_envelope_zstd

Decodes and verifies a durable zstd-compressed WAL segment envelope.

encode_wal_segment_envelope_zstd

Encodes a WAL envelope as its durable zstd-compressed CBOR representation.
