Trait SnapshotStorageTier 

pub trait SnapshotStorageTier<T>: BaseStorageTier
where
    T: Send + Sync + 'static,
{
    // Required methods
    fn save(&self, snapshot: T) -> Result<(), StorageError>;
    fn load(&self) -> Result<Option<T>, StorageError>;
}

Snapshot tier — writes a single record per save(snapshot) call. Mirrors TS SnapshotStorageTier<T>.

Backend key is determined by the tier’s key_of closure (default: a constant tier.name). Successive saves overwrite the same key.

Required Methods

fn save(&self, snapshot: T) -> Result<(), StorageError>

Buffer a snapshot pending flush. Honors compact_every and debounce_ms semantics per the BaseStorageTier contract.

fn load(&self) -> Result<Option<T>, StorageError>

Load the most-recently-saved snapshot. Returns Ok(None) if no snapshot has been persisted yet.
