fn num_joysticks(&self) -> Result<u32, String>

Retreive the total number of attached joysticks and controllers identified by SDL.

fn is_game_controller(&self, joystick_index: u32) -> bool

Return true if the joystick at index joystick_index is a game controller.

fn open(&self, joystick_index: u32) -> Result<GameController, IntegerOrSdlError>

Attempt to open the controller ad index joystick_index and return it. Controller IDs are the same as joystick IDs and the maximum number can be retreived using the SDL_NumJoysticks function.

fn name_for_index(
    &self,
    joystick_index: u32
) -> Result<String, IntegerOrSdlError>

Return the name of the controller at index joystick_index.

fn set_event_state(&self, state: bool)

If state is true controller events are processed, otherwise they're ignored.

fn event_state(&self) -> bool

Return true if controller events are processed.

fn add_mapping(&self, mapping: &str) -> Result<MappingStatus, AddMappingError>

Add a new mapping from a mapping string

fn load_mappings<P: AsRef<Path>>(&self, path: P) -> Result<i32, AddMappingError>
