package async_rpc_kernel

A 'connection_state Implementation.t is something that knows how to respond to one query, given a 'connection_state. That is, you can create a 'connection_state Implementation.t by providing a function which takes a query *and* a 'connection_state and provides a response.

The reason for this is that RPCs often do something like look something up in a master structure. This way, Implementation.ts can be created without having the master structure in your hands.
