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).

Implementations

impl Audience

pub fn disclosure_set(self) -> Vec<Disclosure>

The disclosure classes this audience may see, in Annex XIII order.

pub fn disclosure_key(self) -> String

The disclosure_key for this audience’s classes — the name under which a view served to it is signed and audited.

Two audiences with the same class set would share a key, and that is correct: the artefact describes the data it covers, not who asked.

pub const fn may_see(self, disclosure: Disclosure) -> bool

Whether this audience may see a field of class disclosure.

The whole Art. 77(2) assignment, in one table.
