GraphValidator

oximedia_graph::graph_evaluator

Struct GraphValidator

pub struct GraphValidator;

Expand description

Validates a filter graph for structural correctness.

Implementations§

impl GraphValidator

pub fn has_cycle(graph: &SimpleGraph) -> bool

Return true if the graph has at least one cycle.

Uses DFS with gray/black node colouring (identical to CycleGraph::has_cycle but operating on the SimpleGraph type).

pub fn is_valid_dag(graph: &SimpleGraph) -> bool

Return true if the graph is a valid DAG (no cycles, at least one node).

pub fn source_nodes(graph: &SimpleGraph) -> Vec<NodeId>

Collect all nodes with in-degree 0 (potential source nodes).

pub fn sink_nodes(graph: &SimpleGraph) -> Vec<NodeId>

Collect all nodes with out-degree 0 (potential sink nodes).
