Required Methods

fn setup(&mut self, emitter: Sender<&Event>)

Store emitter to be able to send events later.

fn id(&self) -> String

Plugin-unique identifier. May be used in EventData.target_id.

fn activate(&mut self, canvas: &VirtualCanvas<'_>)

Plugin is starting to be used. Called by user, not other plugins.

fn draw(&self, canvas: &mut VirtualCanvas<'_>)

Plugin may draw some additional overlay there.

fn act(&mut self, ev: &Event, canvas: &mut VirtualCanvas<'_>) -> bool

Return value: whether this plugin consumes the event.

fn deactivate(&mut self)

Plugin is deactivated. It may be activated again later. Called by user, not other plugins.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
