Required methods

fn advance_state(
    state: &mut DecodeState,
    code: u8
) -> Result<Option<KeyEvent>, Error>

Handles the state logic for the decoding of scan codes into key events.

fn map_scancode(code: u8) -> Result<KeyCode, Error>

Convert a Scan Code set X byte to our 'KeyCode' enum

fn map_extended_scancode(code: u8) -> Result<KeyCode, Error>

Convert a Scan Code Set X extended byte (prefixed E0) to our KeyCode enum.
