Struct ColumnRef 

pub struct ColumnRef {
    pub schema: Option<Arc<str>>,
    pub table: Option<Arc<str>>,
    pub column: Arc<str>,
}

A reference to a column, possibly qualified with a table name and, for a three-part schema.table.column reference, a leading database/schema name.

Fields

schema: Option<Arc<str>>

Optional database/schema qualifier — the leading segment of a three-part schema.table.column reference. None for bare and table-qualified references.

table: Option<Arc<str>>

Optional table (or alias) qualifier.

column: Arc<str>

Column name.

Implementations

impl ColumnRef

pub fn bare(column: impl Into<Arc<str>>) -> Self

Create an unqualified column reference (column).

pub fn qualified( table: impl Into<Arc<str>>, column: impl Into<Arc<str>>, ) -> Self

Create a table-qualified column reference (table.column).

pub fn schema_qualified( schema: impl Into<Arc<str>>, table: impl Into<Arc<str>>, column: impl Into<Arc<str>>, ) -> Self

Create a schema-qualified column reference (schema.table.column).

The leading segment names the database/schema (e.g. main, temp, or an attached database alias), matching SQLite’s three-part column syntax.
