Struct CachedEntry 

pub struct CachedEntry {
    pub data: DataTable,
    pub fetched_at: SystemTime,
    pub ttl: Duration,
    pub tags: Vec<String>,
    pub metadata: HashMap<String, Value>,
}

One cached source entry. Cloning is cheap because DataTable is Arc-backed; metadata + tag clones are a small HashMap/Vec.

Fields

data: DataTable

fetched_at: SystemTime

ttl: Duration

tags: Vec<String>

Free-form tags for bulk invalidation. Typical values: ["slug:kyomi-analytics", "namespace:workspace-foo"].

metadata: HashMap<String, Value>

Provider metadata preserved with the cached entry (from FetchResult.metadata). Survives cache hits so callers see the same bytes_billed / rows_returned as on the original fetch.

Implementations

impl CachedEntry

pub fn is_expired(&self) -> bool

true once the entry has aged past its TTL. Conservative — clock regressions or SystemTime errors return true (treat as expired) so we never serve a stale row by accident.

pub fn age(&self) -> Duration

Wall-clock age of the entry. Returns Duration::ZERO if the system clock has gone backwards since the entry was inserted.

Trait Implementations

impl Clone for CachedEntry

fn clone(&self) -> CachedEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CachedEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
