Struct ColumnTypeSchema 

pub struct ColumnTypeSchema<'a> { /* private fields */ }

Zero-allocation view matching RowSchema::with_types for the supplied unqualified column definitions. Names and declared types, including domains and nested arrays, stay borrowed from their existing owner. Duplicate exact names remain ambiguous; dots in an identifier do not create a relation qualifier.

Trait Implementations

impl<'a> Clone for ColumnTypeSchema<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Preserve the physical outer-row interface used by existing custom scalar-subquery resolvers. Declared column views have no query arena or physical outer row.
