[−][src]Struct uniui_core::Signal

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

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>[src]

pub fn new() -> Signal<T>[src]

Creates new instance

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

Connect callback to the Signal

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

Connect Slot to the Signal

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

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[src]

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