Features

type feature =
  1. | Nack_with_list

Any new network-protocol feature should be declared here, and the feature_available function should be updated accordingly. This avoid to clutter the code base with hardcoded version comparisons.

val feature_available : feature -> t -> bool

feature_available feature version returns true if the feature is known to be available for the given p2p protocol version.
