LiveTable

Struct LiveTable 

Source
pub struct LiveTable {
    pub name: String,
    pub rootpage: u32,
    pub column_names: Option<Vec<String>>,
    pub affinities: Vec<Affinity>,
    pub create_sql: String,
}
Expand description

A live (schema-present) table, as read from sqlite_master: its name, b-tree rootpage, and per-column shape used to attribute a freed row whose page linkage is gone.

column_names is Some only when the CREATE TABLE statement parsed with confidence AND its column count equals affinities.len(); otherwise None, so a caller falls back to generic c0..cN rather than risk wrong names. The affinities are always present (one per parsed column) and drive shape matching.

Fields§

§name: String

Table name from sqlite_master.name.

§rootpage: u32

1-based b-tree rootpage from sqlite_master.rootpage.

§column_names: Option<Vec<String>>

Declared column names, or None when low-confidence (caller uses c0..).

§affinities: Vec<Affinity>

Declared column affinity for each column, in column order.

§create_sql: String

The table’s CREATE TABLE statement (sqlite_master.sql), threaded so a consumer can re-derive schema properties (e.g. AUTOINCREMENT-ness via crate::is_autoincrement) without re-reading the schema. Empty when the schema row carried no/invalid sql (a damaged schema).
