Enum ForcedFreshness 

pub enum ForcedFreshness {
    ForceExpired,
    ForceExpiredServeStale {
        expired_at: Option<SystemTime>,
    },
    ForceMiss,
    ForceFresh,
}

Indicators of which level of cache freshness logic to force apply to an asset.

For example, should an existing fresh asset be revalidated or re-retrieved altogether.

Variants

ForceExpired

Indicates the asset should be considered stale and revalidated, with its stale-while-revalidate and stale-if-error windows closed so that readers wait on the revalidation

ForceExpiredServeStale

Indicates the asset should be considered stale, leaving its stale-while-revalidate and stale-if-error windows to decide whether the stale body can still be served while it revalidates

expired_at is when the asset went out of service, such as the timestamp a purge was recorded at. CacheMeta::expire_at applies it and explains why it has to be that point rather than the time of the lookup.

None when the asset is out of service but the caller does not know when it went out, which leaves the windows measured from the asset’s own deadline.

Fields

expired_at: Option<SystemTime>

ForceMiss

Indicates the asset should be considered absent and treated like a miss instead of a hit

ForceFresh

Indicates the asset should be considered fresh despite possibly being stale
