Functions
@spec exists?(ProcessHub.hub_id(), term()) :: boolean()
Returns a boolean indicating whether the key exists in local storage.
@spec get(ProcessHub.hub_id(), term()) :: term()
Returns the value for the key in local storage.
If the key does not exist, nil is returned; otherwise, the value is returned in
the format of a tuple: {key, value, ttl}.
@spec insert(ProcessHub.hub_id(), term(), term(), pos_integer() | nil) :: boolean()

It is possible to set a time to live (TTL) for the key. If the TTL is set to nil, the key will not expire.
The ttl value is expected to be a positive integer in milliseconds.
