Struct EdgeEndpointRule 

pub struct EdgeEndpointRule {
    pub relation: EdgeRelation,
    pub source: EndpointKind,
    pub target: EndpointKind,
}

A pack-declared endpoint rule for a specific edge relation (ADR-031).

Rules are additive: they extend the set of allowed (source, relation, target) triples beyond the ADR-002 base contract. Packs cannot tighten the base rules — only broaden them. The closed EdgeRelation taxonomy itself is not extended; only the endpoint contract per relation is.

Example — GTD pack allows depends_on between task notes:

EdgeEndpointRule {
    relation: EdgeRelation::DependsOn,
    source: EndpointKind::NoteOfKind("task"),
    target: EndpointKind::NoteOfKind("task"),
}

Fields

relation: EdgeRelation

source: EndpointKind

target: EndpointKind

Trait Implementations

impl Clone for EdgeEndpointRule

fn clone(&self) -> EdgeEndpointRule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EdgeEndpointRule

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for EdgeEndpointRule

fn eq(&self, other: &EdgeEndpointRule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
