Enum EdgeEndpointDef 

pub enum EdgeEndpointDef {
    Any,
    NodeType(NodeTypeRef),
    OneOf(SmallVec<[NodeTypeRef; 4]>),
}

Edge endpoint definition.

OneOf carries a sorted, deduplicated, length-≥-2 set of distinct NodeTypeRefs. Construct it via EdgeEndpointDef::one_of so the invariants are enforced (singleton inputs collapse to EdgeEndpointDef::NodeType). The WAL is permissive — recovery re-applies the constructor through the storage-side resolver, so direct struct construction in WAL paths is acceptable and replay canonicalizes.

Variants

Any

Accept any declared node type at this endpoint.

NodeType(NodeTypeRef)

Reference one concrete node type.

OneOf(SmallVec<[NodeTypeRef; 4]>)

Reference any node type drawn from a sorted, deduplicated, length-≥-2 set of distinct node types.

Implementations

impl EdgeEndpointDef

pub fn one_of(refs: impl IntoIterator<Item = NodeTypeRef>) -> Self

Construct an endpoint accepting refs, canonicalized.

References are sorted by database-string identity and deduplicated. A single resulting reference collapses to EdgeEndpointDef::NodeType.

Panics

Panics when the resulting set is empty; zero-label endpoints are a caller bug and the upstream resolver must reject them before reaching this constructor.

Trait Implementations

impl Clone for EdgeEndpointDef

fn clone(&self) -> EdgeEndpointDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeEndpointDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EdgeEndpointDef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EdgeEndpointDef

impl Hash for EdgeEndpointDef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EdgeEndpointDef

fn eq(&self, other: &EdgeEndpointDef) -> 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.

impl Serialize for EdgeEndpointDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
