RowVersion

Struct RowVersion 

Source

    pub rowid: Option<i64>,
    pub values: Vec<Value>,
    pub origin: VersionOrigin,
    pub commit_seq: Option<u32>,
    pub view_state: ViewState,

Expand description

One version of one row: a distinct record value the rowid held at some point, with its evidence-based classification and logical provenance.

Fields§

§rowid: Option<i64>

The rowid this version belongs to. None only for a carved residue whose rowid was destroyed.

§values: Vec<Value>

The decoded column values of this version, in column order.

§origin: VersionOrigin

Logical provenance of the version.

§commit_seq: Option<u32>

The LOGICAL commit sequence (per salt epoch, monotonic WITHIN an epoch only) of the EARLIEST view this value appeared in. None for the live view and for carved residue (order-unknown).

§view_state: ViewState

Evidence-based view state.

§is_deleted: bool

Whether this version’s rowid is absent from the final live view (a deletion or a completed pre-reuse entity).

§is_guessed: bool

Whether this version was reconstructed/guessed rather than read directly (carved residue with inferred attribution).

§rowid_reused: bool

Whether this rowid was REUSED — present, then absent for ≥1 view, then present again with a DIFFERENT record. Set on every version of a reused rowid so a renderer never presents two entities as one continuous update.

§attribution_uncertain: bool

Whether this version’s attribution is uncertain — its source view was checksum-invalid residue, or its schema could not be reconstructed.
