Enum CacheStatus 

pub enum CacheStatus {
    Hit,
    Stale {
        revalidation_task_id: Option<String>,
    },
    Miss,
}

Outcome of a cache-aware fetch.

Stale carries the id of the revalidate task that was enqueued when the SWR fast-path (M6) returned the expired row. None means the row was served stale but the task insert failed (logged; not fatal).

Variants

Fields
