Struct CachePolicy 

pub struct CachePolicy {
    pub ttl: Duration,
    pub dependencies: HashSet<String>,
    pub priority: u8,
    pub sliding: bool,
}

Policy for cache entry behavior

Fields

dependencies: HashSet<String>

Tables/collections this result depends on

priority: u8

Priority for eviction (higher = keep longer)

sliding: bool

Whether to refresh on access (sliding expiration)
