Trait UseStateHandle 

pub trait UseStateHandle<T, G>: HasStateHandle<T, G> + 'static
where
    T: 'static + Clone + Debug + PartialEq + Send + Sync,
    G: 'static + Clone + Debug + Eq + Hash + Send + Sync,
{
    // Provided method
    fn subscribe<'async_trait, S>(
        self: Arc<Self>,
        reader: impl 'async_trait + Into<ReaderEx<S, T>> + Send,
        tag: G,
    ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
       where S: 'static + Clone + Debug + PartialEq + Send + Sync + 'async_trait,
             Self: Sync + Send + 'async_trait { ... }
}

Convenient method to do subscription with a state convert function. The trait is auto implemented for types implemented HasStateHandle.

Provided Methods

fn subscribe<'async_trait, S>( self: Arc<Self>, reader: impl 'async_trait + Into<ReaderEx<S, T>> + Send, tag: G, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where S: 'static + Clone + Debug + PartialEq + Send + Sync + 'async_trait, Self: Sync + Send + 'async_trait,

Do subscription with a state convert function.

• stage [1] – receive from source’s broadcast channel.
• stage [3] – receive from source’s broadcast channel and process it.
• stage [4] – (optional) feedback when the change event has been processed.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
