setup(Mnemonix.Store.options()) :: {:ok, nil}

Skips setup since this store does nothing.

Ignores all opts.

Link to this function start_link(options \\ []) View Source 
start_link(Mnemonix.Supervisor.options()) :: GenServer.on_start()
start_link(Mnemonix.Supervisor.options()) :: GenServer.on_start()

Starts a new store using the Mnemonix.Stores.Null module with options.

The options are the same as described in Mnemonix.Features.Supervision.start_link/2. The :store options are used in config/1 to start the store; the :server options are passed directly to GenServer.start_link/2.

The returned GenServer.server/0 reference can be used as the primary argument to the Mnemonix API.

Examples 

iex> {:ok, store} = Mnemonix.Stores.Null.start_link()
iex> Mnemonix.put(store, "foo", "bar")
iex> Mnemonix.get(store, "foo")
nil

iex> {:ok, _store} = Mnemonix.Stores.Null.start_link(server: [name: My.Mnemonix.Stores.Null])
iex> Mnemonix.put(My.Mnemonix.Stores.Null, "foo", "bar")
iex> Mnemonix.get(My.Mnemonix.Stores.Null, "foo")
nil
