TableHistory

Struct TableHistory 

Source
pub struct TableHistory {
    pub table: String,
    pub columns: Vec<String>,
    pub without_rowid: bool,
    pub versions: Vec<RowVersion>,
    pub without_rowid_rows: Vec<Vec<Value>>,
}
Expand description

The version history of one user table.

Fields§

§table: String

The table’s sqlite_master.name.

§columns: Vec<String>

The table’s column names (real names where the schema parsed, else generic).

§without_rowid: bool

Whether this is a WITHOUT ROWID table — such tables have no rowid and are not version-tracked here; versions is then empty (presence recorded only), and the live rows are carried in without_rowid_rows.

§versions: Vec<RowVersion>

Every row version, sorted by rowid (None last), then commit_seq ascending, with carved-residue (order-unknown) versions grouped after the ordered versions of their rowid.

§without_rowid_rows: Vec<Vec<Value>>

For a WITHOUT ROWID table (§1.4): its live rows read from the index b-tree, in the table’s column order. Empty for an ordinary table and for a WITHOUT ROWID table whose rows could not be read. These have no version history (the model is rowid-keyed); they are the present live state.
