Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> AsAny for T
where T: Any + Send + Sync,

fn any_ref(&self) -> &(dyn Any + Sync + Send + 'static)

Obtains a dyn Any reference to the object: Read more

fn as_any(self: Arc<T>) -> Arc<dyn Any + Sync + Send>
