Struct StateMachine 

pub struct StateMachine<S> { /* private fields */ }

A state machine that holds the stack of states and performs transitions between states. It can be created using

StateMachine::<()>::default()

Generics

• S: State data, the data that is sent to states for them to do their operations.

Implementations

impl<S> StateMachine<S>

pub fn is_running(&self) -> bool

Returns if the state machine still has states in its stack.

pub fn update(&mut self, state_data: &mut S)

Updates the state at the top of the stack with the provided data. If the states returns a transition, perform it.

pub fn push(&mut self, state: Box<dyn State<S>>, state_data: &mut S)

Push a state on the stack and start it. Pauses any previously active state.

pub fn stop(&mut self, state_data: &mut S)

Removes all currently running states from the stack.

Trait Implementations

impl<S> Default for StateMachine<S>

fn default() -> Self

Returns the “default value” for a type.
