source · pub struct CachePolicy(/* private fields */);
Expand description
Represents a serializable configuration for a cache entry in a CacheDb
.
Implementations§
source§impl CachePolicy
impl CachePolicy
sourcepub fn age(&self, now: SystemTime) -> Duration
pub fn age(&self, now: SystemTime) -> Duration
Returns how long the response has been sitting in cache.
sourcepub fn time_to_live(&self, now: SystemTime) -> Duration
pub fn time_to_live(&self, now: SystemTime) -> Duration
Returns approximate time in milliseconds until the response becomes stale.
sourcepub fn is_stale(&self, now: SystemTime) -> bool
pub fn is_stale(&self, now: SystemTime) -> bool
Returns true
if the cache entry has expired.
