Enum PurgeOutcome 

pub enum PurgeOutcome {
    NotFound,
    Purged(Option<CacheEntryId>),
    Expired,
}

Outcome of a successful Storage::purge or Storage::expire call.

Variants

NotFound

Storage did not find the target entry.

Purged(Option<CacheEntryId>)

Storage removed an entry, with the ID selected for an active target, if any.

Exact targets already contain the complete identity and need not repeat their ID here.

Expired

Storage kept the entry and marked it stale.

Only Storage::expire returns this. The entry is still stored, so the eviction manager keeps tracking it.
