Struct SimpleStateImplementation

pub struct SimpleStateImplementation<'a, K, Id, D, E>
where
    D: KeyProvidingData<K>,
    Id: Copy,
{ /* private fields */ }

AutomatonState implementating struct which simplifies state definition by managing list of defined connections. Depends on data for providing next key. This key is then used to match a connection from the defined list. Each state has an assigned identifier which is used to inform which state did the automaton stop on. Identifier is copied to the result meaning it has to implement the Copy trait.

Implementations

impl<'a, K, Id, D, E> SimpleStateImplementation<'a, K, Id, D, E>

where D: KeyProvidingData<K>, Id: Copy,

pub fn new(id: Id) -> Self

Creates new simple state with provided identifier.

• id - Identifier of this state which will be copied into result when automaton stops on this state.

pub fn register_connection( &mut self, connection: SimpleInterStateConnection<'a, K, Id, D, E>, )

Adds connection to possible next states of current state.

Trait Implementations

impl<'a, K, Id, D, E> AutomatonState<'a, Id, D, E> for SimpleStateImplementation<'a, K, Id, D, E>

where D: KeyProvidingData<K>, Id: Copy,

fn get_id_owned(&self) -> Id

Returns owned copy of identifier of this state.

fn get_id(&self) -> &Id

Returns identifier of this state.

fn execute_next_connection( &self, data: &mut D, ) -> Result<NextState<'a, Id, D, E>, E>

Finds connection by popping key from key iterator. Executes assigned function and returns next state if everything goes alright.
