See Supervisor.

@spec query(
  :info | :players | :rules,
  {:inet.ip_address(), :inet.port_number()},
  [{atom(), any()}]
) ::
  {:info, A2S.Info.t()}
  | {:players, A2S.Players.t()}
  | {:rules, A2S.Rules.t()}
  | {:error, any()}

• :name - Alias of the top-level supervisor. Defaults to A2S.Client.

• :timeout - Absolute timeout for the request to complete. Defaults to 5000 or 5 seconds.

@spec start_link(keyword()) :: :ignore | {:error, any()} | {:ok, pid()}

The following configuration options are available:

• :name - Alias of the top-level supervisor. Can be provided if you intend to run multiple client instances. Defaults to A2S_Singleton.

• :port - UDP socket port used for querying game servers. Defaults to 20850.

• :idle_timeout - A2S.Client internally allocates a :gen_statem for each address queried, that should exit after idling to keep from leaking resources. Defaults to 120_000 or 2 minutes.

• :recv_timeout - Timeout the :gen_statem's will wait between receiving individual packets before returning {:error, :recv_timeout}. Defaults to 3000 or 3 seconds.
