Trait PolarsCategoricalType 

pub unsafe trait PolarsCategoricalType: PolarsDataType {
    type Native: NumericNative + CatNative + DictionaryKey + PartialEq + Eq + Hash;
    type PolarsPhysical: PolarsIntegerType<Native = Self::Native>;

    // Required method
    fn physical() -> CategoricalPhysical;
}

Safety

The physical() return type must be correct for Native.

Required Associated Types

type Native: NumericNative + CatNative + DictionaryKey + PartialEq + Eq + Hash

type PolarsPhysical: PolarsIntegerType<Native = Self::Native>

Required Methods

fn physical() -> CategoricalPhysical

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
