Struct GraphOverlay 

pub struct GraphOverlay { /* private fields */ }

Compact edge-visibility mask for graph surgery without cloning adjacency.

A directed edge from → to is visible iff !hide_outgoing(from) && !hide_incoming(to).

Implementations

impl GraphOverlay

pub fn observational(n: usize) -> Self

Observational overlay (all edges visible) for n nodes.

pub fn do_intervention(n: usize, intervened: &[DenseNodeId]) -> Self

Do-intervention overlay: hide all edges into each intervened node.

pub fn remove_outgoing(n: usize, nodes: &[DenseNodeId]) -> Self

Hide all outgoing edges from each node (backdoor / IV mutilation style).

pub fn is_observational(&self) -> bool

Whether every directed edge of the base graph remains visible.

pub fn edge_visible(&self, from: DenseNodeId, to: DenseNodeId) -> bool

Whether directed edge from → to is visible under this overlay.

Trait Implementations

fn clone(&self) -> GraphOverlay

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphOverlay

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

Formats the value using the given formatter.
