Implementations§

Source §

impl MessageHub

Source

pub fn new() -> Arc<Self>

Source

pub fn clone_inner(&self) -> Self

Source

pub fn connect(&self, uuid: Uuid) -> Receiver<DeviceEvent>

Register a new connection, returns a receiver

Source

pub fn disconnect(&self, uuid: &Uuid)

Disconnect a device

Source

pub fn deliver(&self, uuid: &Uuid, event: DeviceEvent)

Deliver an event to a specific device

Source

pub fn deliver_many(&self, uuids: &[Uuid], event: DeviceEvent)

Deliver an event to multiple devices

Source

pub fn is_online(&self, uuid: &Uuid) -> bool

Check if a device is currently online (has an active connection)

Source

pub fn online_count(&self) -> usize

Get count of online devices

Source

pub fn online_devices(&self) -> Vec<Uuid>

Get all online device UUIDs
