-/**
- * An observed callback.
- *
- * Callbacks that are bound to an object are automatically detached when the
- * `ObservableCallbackInterface` and the bound object are out of scope.
- * This means that the `ObservableCallbackInterface` can be ignored if the
- * observed callback should be bound to the lifetime of the object.
- * ```php
- * class Example {
- *     function __construct(MeterProviderInterface $meterProvider) {
- *         $meterProvider->getMeter('example')
- *             ->createObservableGauge('random')
- *             ->observe(fn(ObserverInterface $observer)
- *                     => $observer->observe(rand(0, 10)));
- *     }
- * }
- * ```
- * Keeping a reference to the `ObservableCallbackInterface` within the bound
- * object to gain a more fine-grained control over the life-time of the callback
- * does not prevent garbage collection (but might require cycle collection).
- *
- * Unbound (static) callbacks must be detached manually using
- * {@link ObservableCallbackInterface::detach()}.
- * ```php
- * class Example {
- *     private ObservableCallbackInterface $gauge;
- *     function __construct(MeterProviderInterface $meterProvider) {
- *         $this->gauge = $meterProvider->getMeter('example')
- *             ->createObservableGauge('random')
- *             ->observe(static fn(ObserverInterface $observer)
- *                     => $observer->observe(rand(0, 10)));
- *     }
- *     function __destruct() {
- *         $this->gauge->detach();
- *     }
- * }
- * ```
