pub type ListGetFn = unsafe fn(PtrConst, usize, &'static Shape) -> Option<PtrConst>;Expand description
Get pointer to the element at index in the list, or None if the
index is out of bounds.
The shape parameter is the list’s shape, allowing type-erased implementations
to extract element size from shape.type_params[0].
§Safety
The list parameter must point to aligned, initialized memory of the correct type.
