Enum HintOutcome 

pub enum HintOutcome {
    Corrected,
    AlreadyCurrent,
    UnknownRange,
}

The result of applying an advisory RoutingHint correction to a ClientTopology.

Variants

Corrected

The hint named a newer owner/epoch for a known range; the cached owner was corrected and needs_refresh was raised.

AlreadyCurrent

The cache already held this range at or beyond the hint’s version; nothing changed (an authoritative apply had already overtaken the hint).

UnknownRange

The hint named a range the cache does not know. A hint is never authoritative enough to introduce a range, so no range was created; needs_refresh was raised so the driver polls for the authoritative topology.
