Enum SemanticRole 

#[non_exhaustive]
pub enum SemanticRole {
    Allow,
    Deny,
    Cancel,
    Exit,
    Value,
}

What a control MEANS, independent of how any surface draws it.

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.

Allow

Grants the thing being asked about.

Deny

Refuses it. The fail-closed default for an absent answer.

Cancel

Backs out without deciding.

Exit

Ends the session.

Value

Supplies a value rather than a decision.
