Trait HasSubscription

pub trait HasSubscription: HasStreamType {
    type Subscription<Item: Async>: Async;

    // Required method
    fn subscribe<T>(
        subcription: &Self::Subscription<T>,
    ) -> impl Future<Output = Option<Self::Stream<T>>> + Send
       where T: Async;
}

where T: Async,

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.
