        field: &Field,
        dtype: &DType,
    ) -> VortexResult<ArrowImport>;
}

Plugin layer for importing an Arrow extension-typed array into a Vortex 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, field: &Field, dtype: &DType, ) -> VortexResult<ArrowImport>

Convert an Arrow array into a Vortex array of dtype.

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
