Struct Logical 

pub struct Logical<Logical, Physical>
where
    Logical: PolarsDataType,
    Physical: PolarsDataType,
{
    pub phys: ChunkedArray<Physical>,
    pub dtype: DataType,
    /* private fields */
}

Maps a logical type to a chunked array implementation of the physical type. This saves a lot of compiler bloat and allows us to reuse functionality.

Fields

phys: ChunkedArray<Physical>

dtype: DataType
