Type Alias SnapshotCell 

pub type SnapshotCell = Arc<ArcSwap<CollectionSnapshot>>;

Per-collection lock-free serving snapshot pointer: the single writer stores a new CollectionSnapshot; readers load one without a lock. (ArcSwap<T> stores an Arc<T> internally, so this is one Arc per load.)

Aliased Type

pub struct SnapshotCell { /* private fields */ }
