Variants§
Allow
We can use the item because it is stable or we provided the corresponding feature gate.
Deny
Fields
§
issue: Option<NonZeroU32>
We cannot use the item because it is unstable and we did not provide the corresponding feature gate.
Unmarked
The item does not have the #[stable]
or #[unstable]
marker assigned.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
