Struct Relationship 

pub struct Relationship {
    pub from: EntityId,
    pub to: EntityId,
    pub kind: String,
    pub weight: f32,
}

A directed, typed edge between two entities.

Fields

from: EntityId

Source entity.

to: EntityId

Target entity.

kind: String

Relationship type label (e.g. “KNOWS”, “PART_OF”).

weight: f32

Optional weight for weighted-graph use cases.

Implementations

impl Relationship

pub fn new( from: impl Into<String>, to: impl Into<String>, kind: impl Into<String>, weight: f32, ) -> Self

Construct a new relationship with the given kind and weight.

pub fn is_self_loop(&self) -> bool

Return true if this relationship is a self-loop (from == to).

pub fn reversed(&self) -> Self

Return a new Relationship with from and to swapped.

The kind and weight are preserved unchanged.

pub fn with_weight(self, w: f32) -> Self

Return a copy of this relationship with the weight changed to w.

All other fields (from, to, kind) are cloned unchanged, making this convenient for builder-style graph construction:

use llm_agent_runtime::graph::Relationship;
let rel = Relationship::new("a", "b", "KNOWS", 1.0).with_weight(0.5);
assert_eq!(rel.weight, 0.5);

Trait Implementations

impl Clone for Relationship

fn clone(&self) -> Relationship

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relationship

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Relationship

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Relationship

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

Render as "from --kind(weight)--> to".

For example: "alice --KNOWS(1.00)--> bob".

impl Serialize for Relationship

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
