Checks if the query is already computed and in the cache.
It returns the shard index and a lock guard to the shard,
which will be used if the query is not in the cache and we need
to compute it. Read more

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
