Enum IssueKind 

#[non_exhaustive]
pub enum IssueKind {
    Unknown,
    Retired,
    Custom(String),
}

The kind of an Issue.

#[non_exhaustive]: new failure kinds get their own variant as the crate grows, so a match needs a _ arm. IssueKind::Custom already carries anything an embedder defines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

Not a member of the vocabulary.

Retired

A member, but retired.

Custom(String)

An embedder-defined issue (a dangling reference, a range violation, …), carrying its own rendered message.
