Struct HeteroEdgeType 

pub struct HeteroEdgeType {
    pub source_type: String,
    pub relation: String,
    pub destination_type: String,
}

Describes a typed, directed edge as a (source_type, relation, destination_type) triple.

This mirrors the canonical form used in heterogeneous GNN literature (HAN, HGT, etc.) and knowledge-graph reasoning.

Example

use scirs2_graph::heterogeneous::HeteroEdgeType;

let et = HeteroEdgeType::new("user", "rates", "item");
assert_eq!(et.relation, "rates");

Fields

source_type: String

Entity type of the source node.

relation: String

Name of the relation.

destination_type: String

Entity type of the destination node.

Implementations

impl HeteroEdgeType

pub fn new( source_type: impl Into<String>, relation: impl Into<String>, destination_type: impl Into<String>, ) -> Self

Create a new edge type.

pub fn key(&self) -> String

Canonical string key "src_type/relation/dst_type".

pub fn reversed(&self) -> Self

Return the reversed edge type (swaps source and destination).

Trait Implementations

impl Clone for HeteroEdgeType

fn clone(&self) -> HeteroEdgeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeteroEdgeType

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

Formats the value using the given formatter.

impl Display for HeteroEdgeType

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

Formats the value using the given formatter.

impl Hash for HeteroEdgeType

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 HeteroEdgeType

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