Enum EdgeEndpointDef 

pub enum EdgeEndpointDef {
    Any,
    NodeType(u32),
    OneOf(Vec<u32>),
}

Edge endpoint definition.

OneOf enumerates a sorted, deduplicated set of distinct node-type indices. Construct it via EdgeEndpointDef::one_of to enforce the structural invariants (sorted, deduplicated, length >= 2; singleton collapses to EdgeEndpointDef::NodeType). Direct struct construction is permitted for rkyv/serde decode paths but is rejected by super::GraphTypeDef::validate_ref as defense in depth.

Variants

Any

Accept any declared node type at this endpoint.

NodeType(u32)

Require one concrete node-type index.

OneOf(Vec<u32>)

Accept any node type drawn from a sorted, deduplicated, length >= 2 set of concrete node-type indices.

Implementations

impl EdgeEndpointDef

pub fn one_of(indices: impl IntoIterator<Item = u32>) -> Self

Construct an endpoint accepting indices, canonicalized.

The input is sorted ascending and deduplicated. A single resulting index collapses to EdgeEndpointDef::NodeType so that Eq/Hash and rkyv byte encoding remain stable across construction paths.

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.

pub fn matches_node_type(&self, node_type: u32) -> bool

Return true when this endpoint accepts the observed node-type index.

pub fn overlaps(&self, other: &Self) -> bool

Return true when two endpoint declarations can match a common node type.

pub const fn node_type_index(&self) -> Option<u32>

Return the concrete node-type index when this endpoint resolves to exactly one node type.

Returns None for EdgeEndpointDef::Any and EdgeEndpointDef::OneOf; callers that need to enumerate the candidate set should match the variant explicitly.

Trait Implementations

impl Archive for EdgeEndpointDef

where u32: Archive, Vec<u32>: Archive,

type Archived = ArchivedEdgeEndpointDef

The archived representation of this type.

type Resolver = EdgeEndpointDefResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

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<__D: Fallible + ?Sized> Deserialize<EdgeEndpointDef, __D> for Archived<EdgeEndpointDef>

where u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, Vec<u32>: Archive, <Vec<u32> as Archive>::Archived: Deserialize<Vec<u32>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<EdgeEndpointDef, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for EdgeEndpointDef

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

Formats the value using the given formatter.

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.

impl<__S: Fallible + ?Sized> Serialize<__S> for EdgeEndpointDef

where u32: Serialize<__S>, Vec<u32>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
