Struct Link 

pub struct Link {
    pub id: Id128,
    pub namespace: String,
    pub source: Id128,
    pub target: Id128,
    pub relation: EdgeRelation,
    pub properties: BTreeMap<String, PropertyValue>,
    pub weight: f64,
    pub created_at: Timestamp,
    pub updated_at: Timestamp,
    pub deleted_at: Option<Timestamp>,
}

A directed, typed edge between two entities (or cross-substrate nodes).

weight must be finite and in [0.0, 1.0]. When the serde feature is enabled, deserialization rejects out-of-range or non-finite weights.

Fields

id: Id128

Unique edge identifier.

namespace: String

Namespace that owns and isolates this edge.

source: Id128

Source node identifier.

target: Id128

Target node identifier.

relation: EdgeRelation

Closed relation type that semantically describes this edge.

properties: BTreeMap<String, PropertyValue>

Arbitrary structured metadata attached to this edge.

weight: f64

Numeric edge weight in the range [0.0, 1.0]; 1.0 means definitional strength.

created_at: Timestamp

Wall-clock time when this edge was created.

updated_at: Timestamp

Wall-clock time of the most recent update.

deleted_at: Option<Timestamp>

Set when the edge is soft-deleted; absent means active.

Implementations

impl Link

pub fn is_valid(&self) -> bool

Return true if all numeric fields carry finite, domain-valid values.

• weight must be finite and in [0.0, 1.0].

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Link

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

Formats the value using the given formatter.
