impl CallbackRegistry

pub fn new() -> Self

Creates an empty callback registry.

pub fn register_default_handler(&mut self, callback: TimeEventCallback)

Registers the callback used when no callback exists for a timer name.

pub fn cancel_default_handler(&mut self)

Removes the default callback, preserving all named callbacks.

pub fn register_callback(&mut self, name: Ustr, callback: TimeEventCallback)

Registers a callback for name, replacing any existing callback for that name.

pub fn has_any_callback(&self, name: &Ustr) -> bool

Returns whether a named or default callback is available for name.

pub fn get_callback(&self, name: &Ustr) -> Option<TimeEventCallback>

Returns the callback for name, falling back to the default callback.

pub fn get_handler(&self, event: TimeEvent) -> TimeEventHandler

Creates a handler for event using its named callback or the default callback.

Panics

Panics if neither a named nor default callback exists for the event.
