A serializable snapshot of a `QueryClient`'s cache, as produced by `dehydrate` and consumed by `hydrate`. Typically
transported from server to client (e.g. embedded in server-rendered markup) to seed the client's cache with data
that has already been fetched, avoiding a redundant fetch on the client.
