Expand description

The type that manages connections in the background.

Fields§

§incoming: Fuse<Receiver<Request>>

Incoming requests from the MultiFork.

§handlers: Vec<(ForkId, BackendHandler<RetryBackoffService<RuntimeTransport>, Arc<RetryProvider>>)>

All active handlers.

It’s expected that this list will be rather small (<10).

§pending_tasks: Vec<ForkTask>§forks: HashMap<ForkId, CreatedFork>

All unique forkids mapped to their corresponding backend.

Note: The backend can be shared by multiple ForkIds if the target the same provider and block number.

§flush_cache_interval: Option<Interval>

Optional periodic interval to flush rpc cache.
