Struct WheelJointDef 

pub struct WheelJointDef(/* private fields */);

Wheel (suspension) joint definition (maps to b2WheelJointDef).

Constrains motion along an axis with suspension (spring + damping) and optional motor around the wheel axis. Use with World::create_wheel_joint(_id) or World::wheel(...).build().
