pub fn check(key: &str, v: &PeerVersion, this: &str) -> Option<(Level, String)>Expand description
What borg doctor says of member key’s version beside this node’s (this, on current): a newer
borg (Ok: nothing to do here unless a release has it, update.rs), or an older protocol with what
it misses (Warn: that member has to update). None for a member on this node’s footing.
