Struct RefAdjacency 

pub struct RefAdjacency { /* private fields */ }

Bidirectional ref-edge tracking.

Maintains forward edges (entity -> targets) and reverse edges (target -> sources) for efficient traversal in both directions.

Implementations

impl RefAdjacency

pub fn new() -> Self

Create an empty adjacency index.

pub fn add(&mut self, entity_id: usize, ref_tag: &str, target_ref_val: &str)

Record a ref edge from entity_id via ref_tag to target_ref_val.

pub fn remove(&mut self, entity_id: usize)

Remove all edges originating from entity_id.

Cleans up both forward and reverse indices.

pub fn targets_from( &self, entity_id: usize, ref_type: Option<&str>, ) -> Vec<String>

Get target ref values from an entity, optionally filtered by ref type.

If ref_type is None, returns all targets. Otherwise only targets reachable via the specified ref tag (e.g. “siteRef”).

pub fn sources_to( &self, target_ref_val: &str, ref_type: Option<&str>, ) -> Vec<usize>

Get source entity ids that reference target_ref_val, optionally filtered by ref type.

Trait Implementations

impl Default for RefAdjacency

fn default() -> Self

Returns the “default value” for a type.
