Expand description
Box
<[T]>
(fat pointer to a slice),
but with a guaranteed #[repr(C)]
layout.
§C layout (for some given type T)
typedef struct {
// Cannot be NULL
T * ptr;
size_t len;
} slice_T;
§Nullable pointer?
If you want to support the above typedef, but where the ptr
field is
allowed to be NULL
(with the contents of len
then being undefined)
use the Option< slice_ptr<_> >
type.
Fields§
§ptr: CLayoutOf<NonNullOwned<T>>
Pointer to the first element (if any).
len: CLayoutOf<usize>
Element count
