Function from_raw_parts 

pub const unsafe fn from_raw_parts<'a, T>(
    data: *const T,
    len: usize,
) -> &'a UniqueEntityEquivalentSlice<T>
where
    T: EntityEquivalent,

Forms a slice from a pointer and a length.

Equivalent to slice::from_raw_parts.

Safety

slice::from_raw_parts must be safe to call with data and len. Additionally, all elements in the resulting slice must be unique.
