Expand description
Result of TyCtxt::eval_stability
.
Variants§
Allow
We can use the item because it is stable or we provided the corresponding feature gate.
Deny
We cannot use the item because it is unstable and we did not provide the corresponding feature gate.
Fields
Unmarked
The item does not have the #[stable]
or #[unstable]
marker assigned.
