pub type ListGetMutFn = unsafe fn(PtrMut, usize, &'static Shape) -> Option<PtrMut>;Expand description
Get mutable 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.
