Expand description

Trait for Arrow conversion compute function.

Required Methods§

Source

fn to_arrow( &self, array: A, data_type: &DataType, ) -> VortexResult<Option<ArrowArrayRef>>

Convert the array to an Arrow array of the given type.

Implementation can return None if the conversion cannot be specialized by this encoding. In this case, the default conversion via to_canonical will be used.

Provided Methods§

Source

fn preferred_arrow_data_type(&self, _array: A) -> VortexResult<Option<DataType>>

Return the preferred Arrow DataType of the encoding, or None of the canonical DataType for the array’s Vortex vortex_dtype::DType should be used.
