Struct ColumnDef 

pub struct ColumnDef {
    pub name: Box<str>,
    pub ty: ValueType,
    pub optional: bool,
}

Static, build-time column metadata (spec 05 §4.1). The ONLY place a column name lives; the index into a &[ColumnDef] IS the [ColId]. optional drives the start-bound nullable-aware = vs IS / <,> vs (… IS NULL OR …) lowering (§3.7); ty drives the value boundary (to_sqlite_param and the leaf’s col() conversion).

Fields

name: Box<str>

ty: ValueType

optional: bool
