A Processor is a module which processes structured log * messages into strings. This is used as part of defining * a Consumer.

module Transport : sig ... end

A Transport is a module which represent a destination * for a log strings. This is used as part of defining a * Consumer.

module Consumer_registry : sig ... end

The Consumer_registry is a global registry where consumers * of the Logger can be registered. Each Consumer consists of * a Processor and a Transport. The processor filters and * serializes structured log messages to strings, and the * transport encapsulates the side effects of the consumer. * Every Consumer is registered under some unique id to * ensure the code does not accidentally attach the same * consumer multiple times.
