impl_datum_type_copy 🔒: Macro to derive InputDatumType and OutputDatumType for all Datum variants that are simple Copy types
impl_tuple_input_datum_type 🔒

ArrayRustType: A new type that wraps a Vec that is used to differentiate the target Datum between Arrays and Lists. The target of this type is Array.
ExcludeNull: A wrapper type that excludes NULL values, even if B allows them.
Int2Vector: PostgreSQL’s int2vector type: a thin wrapper over a 1-dimensional Array of int2, kept distinct from a regular int2[] array because it forbids NULL elements.
OptionalArg: Wrapper to distinguish “argument may not be present” from Option<T> (nullable).
PropArray
PropDict
PropList
PropRange
Variadic: A wrapper type for variadic arguments that consumes the remaining iterator.

AsColumnType: Types that implement this trait can be stored in an SQL column with the specified SqlColumnType
InputDatumType: A bridge between native Rust types and SQL runtime types represented in Datums
OutputDatumType: A bridge between native Rust types and SQL runtime types represented in Datums
SqlContainerType: Trait for SQL container types whose element/value type can be extracted from or wrapped into a SqlScalarType.
