Expand description
Like slice_ref
and slice_mut
, but with any lifetime attached
whatsoever.
It is only intended to be used as the parameter of a callback that
locally borrows it, due to limitations of the [ReprC
][
trait@crate::layout::ReprC
] design w.r.t. higher-rank trait bounds.
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: NonNull<T>
Pointer to the first element (if any).
