impl Storage for NoStorage

type Config = ()

type Segment = SealedSegment<File>

fn store( &self, _namespace: &NamespaceName, _seg: Self::Segment, _config: Option<Self::Config>, _on_store: OnStoreCallback, )

store the passed segment for namespace. This function is called in a context where blocking is acceptable. returns a future that resolves when the segment is stored The segment should be stored whether or not the future is polled.
