Struct VersionChange 

pub struct VersionChange { /* private fields */ }

A change in version of an interface.

This structure is used to validate that the new version of an interface is a valid successor of the previous version. The version cannot decrease, and they cannot be the same (not really a version change).

This validates only the version change, not the interface itself. For that, see Interface::validate_with.
