Function binary_unchecked_same_type 

pub unsafe fn binary_unchecked_same_type<T, U, F>(
    lhs: &ChunkedArray<T>,
    rhs: &ChunkedArray<U>,
    op: F,
    keep_sorted: bool,
    keep_fast_explode: bool,
) -> ChunkedArray<T>
where
    T: PolarsDataType,
    U: PolarsDataType,
    F: FnMut(&T::Array, &U::Array) -> Box<dyn Array>,

Applies a kernel that produces ArrayRef of the same type.

Safety

Caller must ensure that the returned ArrayRef belongs to T: PolarsDataType.
