Trait that State types have to implement

Associated Types

type Value: Clone + Display

Type that is stored in the State variable.

type Store

Type that is wrapped in Arc which stores the value.

type Channel: Clone

Channel type is used to pass the message between the Sender and the Receiver.

Required methods

fn value(&self) -> Self::Value

Returns a copy of the original value stored.

fn tx(&self) -> StateSender<Self::Channel>

Returns the clone of the Sender.

fn rx(&self) -> StateReceiver<Self::Channel>

Returns the clone of the Receiver.

fn put(&self, value: Self::Value)

Stores the value on to the State variable.

fn pointer(&self) -> Arc<Self::Store>

Gives a pointer to the value.

fn update(&self)

Update the value across the DOM. put() should call this.
