Struct medea_jason::utils::component::Component

pub struct Component<S, O> { /* private fields */ }

Component is a base that helps managing reactive components.

It consists of two parts: state and object. Object is listening to its state changes and updates accordingly, so all mutations are meant to be applied to the state.

Implementations

impl<S, O> Component<S, O>

pub fn obj(&self) -> Rc<O>

Returns Rc to the object managed by this Component.

pub fn state(&self) -> Rc<S>

Returns reference to the state of this Component.

impl<S: ComponentState<O> + 'static, O: 'static> Component<S, O>

pub fn new(obj: Rc<O>, state: Rc<S>) -> Self

Returns new Component with a provided object and state.

Spawns all watchers of this Component.

impl Component<State, Repository>

pub fn get(&self, id: PeerId) -> Option<Rc<PeerConnection>>

Returns PeerConnection stored in the repository by its ID.

pub fn get_all(&self) -> Vec<Rc<PeerConnection>>

Returns all PeerConnections stored in the repository.

pub fn connection_lost(&self)

Notifies all peer::Components about a RPC connection loss.

pub fn connection_recovered(&self)

Notifies all peer::Components about a RPC connection restore.

pub fn apply(&self, new_state: Room)

Updates this State with the provided proto::state::Room.
