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

§feature: Symbol
§reason: Option<Symbol>
§issue: Option<NonZero<u32>>
§suggestion: Option<(Span, String, String, Applicability)>
§is_soft: bool
§

Unmarked

The item does not have the #[stable] or #[unstable] marker assigned.
