Enum Audience 

#[non_exhaustive]
pub enum Audience {
    Public,
    LegitimateInterest,
    Authority,
}

Re-export the canonical access vocabulary from dpp-domain. Who is asking for passport data.

Regulation (EU) 2023/1542 Art. 77(2) names three audiences and assigns each a set of Annex XIII data points:

Audience	Annex XIII
(a) general public	1
(b) notified bodies, market surveillance authorities, the Commission	2 and 3
(c) persons with a legitimate interest	2 and 4

This is a lattice, not a ranking. Point 3 (conformity test reports) is authority-only; point 4 (individual-item use history) is legitimate-interest-only. Neither audience contains the other, so no integer ordering can express the assignment: any >= comparison necessarily either hands authorities the individual-item data Art. 77(2)(b) withholds, or hides point-2 data from someone entitled to 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.

Public

Anyone, with no credential. Art. 77(2)(a).

LegitimateInterest

A repairer, remanufacturer, second-life operator or recycler holding a credential that proves the interest. Art. 77(2)(c).

Authority

Notified body, market surveillance authority, customs, or the Commission. Art. 77(2)(b).
