currently I cant figure out the proper way to call eval:

test "should eval expression", %{t: t} do
    Tarantool.Api.eval(t, %{expr: 'return "hola"', tuple: [""]}) |> IO.inspect()  
end
>> {:error, 32788, "Invalid MsgPack - packet body"}

Any help / docs on this?

Since I'm both new to Tarantool and Elixir, I had issues with using your client. Is it functional or am I using it wrong?

I notice that calls to query operations like SELECT, INSERT, etc requires 2 parameters: a socket connection, and a tuple. Where do we get the connection?

Are we supposed to run it like so:

{:ok, pid} = Tarantool.start_link()

and then use the pid in another call? I didn't quite understand how the macro code works. Please show a simple example usage for each operation.

If I only know space name, how am I supposed to use the API?
