Trait polars::datatypes::PolarsDataType

pub unsafe trait PolarsDataType: Send + Sync + Sized {
    type Physical<'a>;
    type Array: for<'a> StaticArray<ValueT<'a> = Self::Physical<'a>>;

    // Required method
    fn get_dtype() -> DataType
       where Self: Sized;
}

Safety

The StaticArray and dtype return must be correct.

Required Associated Types

type Physical<'a>

type Array: for<'a> StaticArray<ValueT<'a> = Self::Physical<'a>>

Required Methods

fn get_dtype() -> DataTypewhere Self: Sized,
