Trait Observe

Source 
pub trait Observe<T>: Sized {
    // Required methods
    fn get(&self) -> Ref<'_, T>;
    fn subscribe(&self, cb: Box<dyn Fn()>) -> ListenerHandle;
    fn once(&self, cb: Box<dyn Fn()>) -> ListenerHandle;
    fn unsubscribe(&self, handle: ListenerHandle) -> bool;
}

Source

fn get(&self) -> Ref<'_, T>

fn subscribe(&self, cb: Box<dyn Fn()>) -> ListenerHandle

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
