Struct StateStore 

pub struct StateStore<Id, S> { /* private fields */ }

StateStore is the storage layer for all state machines associated with a given manager. Every state tree is associated with a particular Mutex this allows separate state hirearchies to be acted upon concurrently while making operations in a particular tree blocking

Implementations

impl<K: Rex> StateStore<StateId<K>, K::State>

pub fn new() -> Self

pub fn new_tree( node: Node<StateId<K>, K::State>, ) -> Arc<FairMutex<Node<StateId<K>, <K as Kind>::State>>>

Panics

Will panic if StateId is nil

pub fn insert_ref( &self, id: StateId<K>, node: Arc<FairMutex<Node<StateId<K>, <K as Kind>::State>>>, )

insert node creates a new reference to the same node

Panics

Will panic if StateId is nil

pub fn remove_ref(&self, id: StateId<K>)

Panics

Will panic if StateId is nil

pub fn get_tree( &self, id: StateId<K>, ) -> Option<Arc<FairMutex<Node<StateId<K>, <K as Kind>::State>>>>

Panics

Will panic if StateId is nil

Trait Implementations

impl<K> Default for StateStore<StateId<K>, K::State>

where K: Rex,

fn default() -> Self

Returns the “default value” for a type.
