Module segment 

SSG2 rows segments (SPEC.md §5.2) and the §2.4 generated-row codec they embed. All structural decode failures are sync.invalid_request (§5.2 error-code rule); the column-table-vs-generated-schema comparison (sync.schema_mismatch) is the receiver’s job, not the codec’s.

Structs

Column

RowsSegment

SegmentRow

One §5.2 row record: the row’s server_version (≥ 1) plus its values.

Enums

ColumnType

Column type tags (§2.4) — unchanged from v1’s binary-table-v1 assignment.

ColumnValue

A decoded column value. Json keeps the raw string (round-trip fidelity).

Constants

SSG2_FORMAT_VERSION

SSG2_MAGIC

Functions

decode_row

Decode one row per the §2.4 row codec: null bitmap (LSB-first, byte i/8), then non-null values positionally in column order.

decode_rows_segment

Decode a complete SSG2 rows segment (§5.2). Structural validation only — exactly the closed §5.2 failure list, every failure sync.invalid_request.

encode_row

Encode one row canonically per §2.4.

encode_rows_segment

Canonically encode a rows segment (§5.2).

Type Aliases

Row

One row: columns.len() slots, None = NULL.
