        dtype: &ExtDTypeRef,
    ) -> VortexResult<ArrowImport>;
}

Plugin layer for importing an Arrow extension-typed array into a Vortex extension array.

Plugins are dispatched by arrow_ext_id.

This is purely an implementation trait, its methods should not be called directly. Instead, use the methods on ArrowSession.

Required Methods

fn arrow_ext_id(&self) -> Id

The Arrow extension name this plugin handles.

fn from_arrow_field(&self, field: &Field) -> VortexResult<Option<DType>>

Build the Vortex DType that corresponds to field (which carries this plugin’s Arrow extension metadata).

fn from_arrow_array( &self, array: ArrowArrayRef, dtype: &ExtDTypeRef, ) -> VortexResult<ArrowImport>

Convert an Arrow array into a Vortex extension array of dtype.

Returns ownership of array via ArrowImport::Unsupported when the plugin cannot handle the input.
