pub struct EntityPolicyConfig {
pub ttl: Option<Duration>,
pub stale_ttl: Option<Duration>,
}Expand description
Configuration for entity caching TTLs.
Specifies how long cached entries should live and when they become stale.
Used by CacheableResponse::cache_policy
to set timestamps on cached values.
§Fields
ttl- Time until the entry expires (becomes invalid)stale_ttl- Time until the entry becomes stale (should refresh in background)
§Example
use hitbox_core::EntityPolicyConfig;
use std::time::Duration;
// Expire after 1 hour, become stale after 5 minutes
let config = EntityPolicyConfig {
ttl: Some(Duration::from_secs(3600)),
stale_ttl: Some(Duration::from_secs(300)),
};
// No expiration (cached forever until manually invalidated)
let forever = EntityPolicyConfig::default();Fields§
§ttl: Option<Duration>Time until cached entries expire and become invalid.
stale_ttl: Option<Duration>Time until cached entries become stale (for background refresh).
