Required methods

fn winding_order(&self) -> Option<WindingOrder>[src]

Return the winding order of this object if it contains at least three distinct coordinates, and None otherwise.

fn points_cw(&self) -> Points<'_, Self::Scalar>ⓘ

Notable traits for Points<'a, T>

impl<'a, T> Iterator for Points<'a, T> where
    T: CoordNum,  type Item = Point<T>;
[src]

Iterate over the points in a clockwise order

The object isn’t changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear clockwise

fn points_ccw(&self) -> Points<'_, Self::Scalar>ⓘ

Notable traits for Points<'a, T>

impl<'a, T> Iterator for Points<'a, T> where
    T: CoordNum,  type Item = Point<T>;
[src]

Iterate over the points in a counter-clockwise order

The object isn’t changed, and the points are returned either in order, or in reverse order, so that the resultant order makes it appear counter-clockwise

fn make_cw_winding(&mut self)[src]

Change this objects’s points so they are in clockwise winding order

fn make_ccw_winding(&mut self)[src]

Change this line’s points so they are in counterclockwise winding order

Provided methods

fn is_cw(&self) -> bool[src]

True iff this is wound clockwise

fn is_ccw(&self) -> bool[src]

True iff this is wound counterclockwise

fn clone_to_winding_order(&self, winding_order: WindingOrder) -> Self where
    Self: Sized + Clone, [src]

Return a clone of this object, but in the specified winding order

fn make_winding_order(&mut self, winding_order: WindingOrder)[src]

Change the winding order so that it is in this winding order
