Required Methods

fn forward<T: Into<Distance>>(&mut self, distance: T)

Move turtle forward by specified distance.

fn move_forward<T: Into<Distance>>(&mut self, distance: T)

Move turtle forward by specified distance without drawing.

fn rotate<T: Into<Degree>>(&mut self, angle: T)

Rotate around angle. If angle is positive, the turtle is turned to the left, if negative, to the right.

fn is_pen_down(&self) -> bool

Returns true if pen is down.

fn pen_down(&mut self)

Put the pen down.

fn pen_up(&mut self)

Put the pen up.

fn goto(&mut self, pos: Position)

fn push(&mut self)

Push current turtle state on stack.

fn pop(&mut self)

Restore previously saved turtle state.

Provided Methods

fn backward<T: Into<Distance>>(&mut self, distance: T)

Move turtle backward by specified distance.

fn right<T: Into<Degree>>(&mut self, angle: T)

Turn turtle right by angle degree.

fn left<T: Into<Degree>>(&mut self, angle: T)

Turn turtle left by angle degree.

fn is_pen_up(&self) -> bool

Returns true if pen is up.

fn home(&mut self)
