Detailed Description

lib/pubsub: Publish-subscribe message passing.

This module wraps the lib/dispatch module, to provide a more ergonomic and type-safe approach to message passing.

In general, we favor this mechanism for cases where higher-level modules need to be notified when something happens in lower-level modules. (The alternative would be calling up from the lower-level modules, which would be error-prone; or maintaining lists of function-pointers, which would be clumsy and tend to complicate the call graph.)

See pubsub.c for more information.
