Struct NoAction 

pub struct NoAction;

A unit action for automatons that need no external action per step.

Also implements Automaton as a no-op — useful for mapping-only servos where the automaton output is irrelevant.

Trait Implementations

impl Automaton for NoAction

type Internal = ()

The automaton’s internal state, carried across step invocations.

type Action = ()

An optional action type driving state transitions on each step.

fn step( &self, _internal: &mut Self::Internal, _current: &ParamValue, _time: Time, _action: &Self::Action, ) -> ParamValue

Advances the automaton by one step, producing a new output value.

fn initial_internal(&self) -> Self::Internal

Returns the automaton’s initial internal state (at time zero).

fn name(&self) -> &str

Returns the human-readable name of this automaton.

fn reset(&self) -> Self::Internal

Resets the automaton to its initial internal state.

impl Clone for NoAction

fn clone(&self) -> NoAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoAction

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

Formats the value using the given formatter.

impl Default for NoAction

fn default() -> NoAction

Returns the “default value” for a type.
