Core step trait - all traversal steps implement this

Required Methods§

Source

fn id(&self) -> &str

Step identifier (unique in traversal)

Source

fn name(&self) -> &str

Human-readable name

Source

fn labels(&self) -> &[String]

Labels assigned to this step

Source

fn add_label(&mut self, label: String)

Add a label to this step

Source

fn requirements(&self) -> &[TraverserRequirement]

Requirements this step declares

Source

fn process_traverser(&self, traverser: Traverser) -> StepResult

Process a single traverser (standard algorithm)

Source

fn reset(&mut self)

Reset step state for reuse

Source

fn clone_step(&self) -> Box<dyn Step>

Clone as trait object

Source

fn as_any(&self) -> &(dyn Any + 'static)
