Struct UiServiceRegistration

pub struct UiServiceRegistration<A> { /* private fields */ }

RAII lifetime for one UI-thread background-service registration.

Dropping the guard unregisters its tree-scoped weak callback when the runtime still exists. Keeping the guard alone does not keep either the callback or runtime alive.

Examples

use std::rc::Rc;
use ailloli_ui_runtime::app::RuntimeHandle;
let runtime = RuntimeHandle::<()>::new();
let callback: Rc<dyn Fn() -> bool> = Rc::new(|| true);
let registration = runtime.register_ui_service(&callback);
assert!(format!("{registration:?}").contains("UiServiceRegistration"));

Trait Implementations

impl<A> Debug for UiServiceRegistration<A>

Omits callback/runtime internals while exposing diagnostic IDs.

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats registration/tree IDs while deliberately omitting runtime state.

impl<A> Drop for UiServiceRegistration<A>

Unregisters the service if its runtime is still alive.

fn drop(&mut self)

Performs best-effort weak-runtime unregistration.
