Modules

  • motors
    Container module for motor types
  • sensors
    Container module for sensor types
  • sound
    Sound-related functions. It can beep, play wav files, or convert text to speech.
  • wait
    Utility functions for cpu efficient wait commands. Uses the libc::epoll_wait that only works on linux systems.

Macros

  • dc_motor
    The DcMotor provides a uniform interface for using regular DC motors with no fancy controls or feedback. This includes LEGO MINDSTORMS RCX motors and LEGO Power Functions motors.
  • findable
    Helper to create a new Device instance.
  • sensor_mode
    Add a sensor mode constant with getter and setter
  • servo_motor
    The ServoMotor provides a uniform interface for using hobby type servo motors.
  • tacho_motor
    The TachoMotor provides a uniform interface for using motors with positional and directional feedback such as the EV3 and NXT motors. This feedback allows for precise control of the motors.

Structs

  • Attribute
    A wrapper to a attribute file in the /sys/class/ directory.
  • Buttonev3
    Ev3 brick button handler. Opens the corresponding /dev/input file handlers.
  • Driver
    Helper struct that manages attributes. It creates an Attribute instance if it does not exists or uses a cached one.
  • Ledev3
    The led’s on top of the EV3 brick.
  • PowerSupply
    An interface to read data from the system’s power_supply class. Uses the built-in legoev3-battery if none is specified.
  • Screenscreen
    Represents the device screen. Advanced drawing operations can be performed with the imageproc crate.

Enums

  • Ev3Error
    Custom error type for internal errors.
