Static Public Member Functions
static unordered_map< idx_t, const shared_ptr< ArrowTypeExtensionData > >	GetExtensionTypes (ClientContext &context, const vector< LogicalType > &duckdb_types)
	This function returns possible extension types to given DuckDB types.

Public Attributes
cast_arrow_duck_t	arrow_to_duckdb = nullptr
	(Optional) Callback to function that converts an Arrow Array to a DuckDB Vector
cast_duck_arrow_t	duckdb_to_arrow = nullptr
	(Optional) Callback to function that converts a DuckDB Vector to an Arrow Array

Private Attributes
LogicalType	duckdb_type
	Original DuckDB Type (e.g., UHUGEINT)
LogicalType	internal_type
	Internal type is a type that refers to the produced duckdb vector when consuming the arrow format.
