Struct StateContainer

pub struct StateContainer { /* private fields */ }

State management for Orbit applications

This is the original state management system that is being enhanced with the reactive system. It’s kept for backward compatibility but new code should prefer the reactive system.

Implementations

impl StateContainer

pub fn new() -> Self

Create a new state container

pub fn create<T: 'static + Clone + Send + Sync>(&self, initial: T) -> State<T>

Create a new state value

pub fn computed<T, F>( &self, compute: F, dependencies: Vec<TypeId>, ) -> Computed<T>

where T: 'static + Clone + Send + Sync, F: Fn() -> T + Send + Sync + 'static,

Create computed state dependent on other state

pub fn subscribe<T: 'static + Send + Sync, F: Fn() + Send + Sync + 'static>( &self, callback: F, )

Subscribe to state changes

pub fn notify(&self, type_id: TypeId)

Notify subscribers of a change to a value
