Enum EdgeKind 

pub enum EdgeKind {
    SameIdentity,
    WorksAt,
    MemberOf,
    EmployedBy,
    SubjectOf,
}

The closed v1 cross-service edge-kind registry (cross-service-linking.md §9). Each kind fixes its endpoint types, direction, temporality, inverse label, and sensitivity.

Variants

SameIdentity

person ↔ worker — the same human across the two registries (symmetric; the federation backbone powering single-view).

WorksAt

person → organization — a person works at an organization.

MemberOf

person → organization — a person is a member of an organization.

EmployedBy

worker → organization — a worker is employed by an organization (carries a role).

SubjectOf

case → person — a case is about / has as its subject a person (high sensitivity — §10).

Implementations

impl EdgeKind

pub const ALL: [EdgeKind; 5]

Every edge kind, in a stable order.

pub const fn as_str(self) -> &'static str

The wire token for this kind.

pub fn from_token(token: &str) -> Option<Self>

Parse a wire token into an EdgeKind, or None if unknown.

pub const fn is_symmetric(self) -> bool

true for a symmetric kind (same_identity): direction is irrelevant and the aggregator canonicalises the pair.

pub const fn is_temporal(self) -> bool

true if the edge is time-bounded (valid_from/valid_to meaningful — affiliations). subject_of is “sometimes”; modelled here as time-bounded-capable.

pub const fn inverse(self) -> Option<&'static str>

The inverse-direction label the aggregator stores for the far endpoint, or None for a symmetric kind (its own inverse).

pub const fn sensitivity(self) -> Sensitivity

This kind’s sensitivity tier.

pub fn permits(self, from: EntityType, to: EntityType) -> bool

Validate that from/to are the endpoint types this kind permits (§9). For the symmetric same_identity, either ordering of {person, worker} is accepted.

Trait Implementations

impl Clone for EdgeKind

fn clone(&self) -> Self

impl Ord for EdgeKind

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
