Trait eventbus::Event

pub trait Event: 'static {
    fn cancellable(&self) -> bool { ... }
    fn cancelled(&self) -> bool { ... }
    fn set_cancelled(&mut self, cancel: bool) { ... }
}

Basic trait for defining an event.

Provided Methods

fn cancellable(&self) -> bool

Returns whether this event is cancellable.

When this is true, cancelled and cancel should also be implemented.

Note: While this method does take a &self, it’s a logic error for an event’s cancellability to change based on its value. The &self is just for trait objectification. You have been warned!

fn cancelled(&self) -> bool

Returns whether this event has been cancelled.

fn set_cancelled(&mut self, cancel: bool)

Sets whether this event is cancelled.

Panics

Panics if this event is not cancellable.
