Struct CachedResult 

pub struct CachedResult {
    pub result: Arc<Vec<JsonbValue>>,
    pub accessed_views: Box<[String]>,
    pub cached_at: u64,
    pub ttl_seconds: u64,
    pub entity_refs: Box<[(String, String)]>,
    pub is_list_query: bool,
}

Cached query result with metadata.

Stores the query result along with tracking information for TTL expiry, view-based invalidation, and monitoring.

Fields

result: Arc<Vec<JsonbValue>>

The actual query result (JSONB array from database).

Wrapped in Arc for cheap cloning on cache hits (zero-copy).

accessed_views: Box<[String]>

Which views/tables this query accesses.

Format: vec!["v_user", "v_post"]

Stored as a boxed slice (no excess capacity) since views are fixed at put() time and never modified.

cached_at: u64

When this entry was cached (Unix timestamp in seconds).

Wall-clock timestamp for debugging. TTL enforcement is handled by moka internally via CacheEntryExpiry.

ttl_seconds: u64

Per-entry TTL in seconds.

Overrides CacheConfig::ttl_seconds when set via put(..., Some(ttl)). Read by CacheEntryExpiry::expire_after_create to tell moka the expiry.

entity_refs: Box<[(String, String)]>

Entity references for selective entity-level invalidation.

Contains one (entity_type, entity_id) pair per row in result that has a valid string in its "id" field. Empty for queries with no id column or when put() is called without an entity_type. Used by the eviction listener to clean up entity_index on eviction.

is_list_query: bool

True when result.len() > 1 at put time.

Used by invalidate_list_queries() to avoid evicting single-entity point-lookup entries on CREATE mutations.
