I'm a bit confused by the second snippet for the sharded DB. Where does the hash function come from? Or is it supposed to be pseudocode?

let shard = db[hash(key) % db.len()].lock().unwrap();
shard.insert(key, value);

You'll have to choose a hash function that is appropriate for whatever the type of key is. There are many different hash functions out there, and the example will work for whichever choice you make.

Thanks for the response! I see, yeah, I guess I was confusing that function with the default HashMap hash function 😅
