Method as_slice

src/array.rs:749–764

Returns an immutable view of the internal data as a slice. # Safety Calling this method is undefined behaviour if the underlying array is aliased mutably by other instances of `PyArray` or concurrently modified by Python or other native code. Please consider the safe alternative [`PyReadonlyArray::as_slice`].
