Module core 

The sans-io cores of the Bybit connectors.

A core is a state machine without sockets, tasks or clocks. It gets inbound frames and the current time, and it pushes events. The connectors in this crate run one core each (MdCore and UdCore) inside a pump task. You can also drive a core by hand, for a test or a replay of recorded frames: the trait [brokapi_sansio::BrokerCore] is the interface.

The stream of Bybit names every data frame with its topic (orderbook.50.BTCUSDT, order.linear) and answers a subscription with a frame that carries the req_id of the request. So a core does not guess which subscription a frame is for: the connector registers the topics of each subscription (MdCore::register, UdCore::register) before it sends the request, and the core looks the frame up.
