Struct Signal

pub struct Signal<T> { /* private fields */ }

Signal can be used to inform others that new data is available.

There is two generic ways to subscribe for new data notificaitons:

• callback - the callback (FnMut) will be triggered every time new data value will be emitted,
• Slot - new data will be added to the Slot’s queue. The Slot have to be pulled to obtain queued data.

Implementations

impl<T: 'static + Clone> Signal<T>

pub fn new() -> Signal<T>

Creates new instance

pub fn connect_func<F: 'static + FnMut(&T)>(&mut self, f: F)

Connect callback to the Signal

pub fn connect_slot(&mut self, slot: &dyn Slot<T>)

Connect Slot to the Signal

pub fn emit(&mut self, t: T)

Emit signal. During the call all related callbacks will be activated and data will be pushed to Slots’ queues.

pub fn has_connections(&self) -> bool

Shows if signal connected to any callback and/or Slot.

Trait Implementations

impl<T: Default> Default for Signal<T>

fn default() -> Signal<T>

Returns the “default value” for a type.
