Speaking of re-inventing the wheel, I based my RPC handler on the
rabbit_management module, which included a fair amount of copy and
paste. Since rabbit_management is an implementation of the gen_server
behaviour, I was wondering if there is any merit in abstracting out
the template callbacks (i.e. handle_management_message() and reply()
), so that this could be more reuseable with different (a) server
functionality and (b) different wireformats. At the moment, this
module can only invoke rabbitmq management calls ( point (a) ) and
only works with JSON ( point (b) ). I don't whether you can have a
behaviour within a behaviour or whether you can have a parameterizable
gen_server implementation.
