Function append_log_storage 

pub fn append_log_storage<B, T, C>(
    backend: Arc<B>,
    opts: AppendLogStorageOptions<T, C>,
) -> AppendLogStorage<B, T, C>
where
    B: StorageBackend + ?Sized,
    T: Serialize + DeserializeOwned + Clone + Send + Sync + 'static,
    C: Codec<Vec<T>>,

Factory: wrap a backend as an append-log tier.

Panics

Panics if opts.compact_every == Some(0). See snapshot_storage for the rationale (pre-1.0 footgun guard per /qa A4).
