Trait SubscribeChain 

pub trait SubscribeChain {
    type Client: Subscribe;
    type Header: DeserializeOwned;

    // Required method
    fn subscribe_finalized_heads<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<<Self::Client as Subscribe>::Subscription<Self::Header>>> + 'async_trait>>

Dyn Compatibility

This trait is dyn compatible.

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