const VERSION: u32

Maximum supported version of this interface

This is the maximum version supported by the protocol specification currently used by this library, and should not be used as-is in your code, as a version change can subtly change the behavior of some objects.

Server are supposed to be able to handle all versions from 1 to the one they advertise through the registry, and clients can choose any version among the ones the server supports.
