Struct State 

pub struct State<Substates: ModelState> {
    pub uid_source: Uid,
    pub substates: Vec<Substates>,
    /* private fields */
}

State struct encapsulates the state-machine’s state.

This includes a Uid generator, a vector of one or more Substates instances, and the current_instance field holding the index of the currently active instance in the state-machine’s main loop.

In most scenarios, the Substates vector contains a single element. Multiple elements mainly occur in testing scenarios where multiple instances are simulated.

Fields

uid_source: Uid

substates: Vec<Substates>

Implementations

impl<Substates: ModelState> State<Substates>

pub fn new() -> Self

pub fn new_uid(&mut self) -> Uid

Generates a new unique identifier (Uid).

pub fn get_current_instance(&self) -> usize

pub fn set_current_instance(&mut self, instance: usize)

pub fn substate<T: 'static + Any>(&self) -> &T

Returns a reference to the state of the currently active substate.

pub fn substate_mut<T: 'static + Any>(&mut self) -> &mut T

Returns a mutable reference to the state of the currently active substate.
