Struct BoundVirtualColumn 

pub struct BoundVirtualColumn {
    pub column: u16,
    pub expr: BoundExpr,
}

A VIRTUAL generated column whose value a write has to look at.

A virtual column is in no record, so the row a write builds does not hold it. NOT NULL and a STRICT table’s type check test the value that would be read back, which has to be computed from the row. Only the columns that declare one of those are here, so a table with no such column carries an empty vector and the write path does nothing extra.

Fields

column: u16

The column, by declared position.

expr: BoundExpr

The column’s value as it is read: the expression, converted by the column’s affinity.
