Expand description

One piece of a fitted outline.

Variants§

Line

A straight piece.

Fields

§from: Point2

Where it starts.

§to: Point2

Where it ends.

Arc

A circular arc, counter-clockwise for a positive sweep.

Fields

§centre: Point2

Its centre.

§radius: f64

Its radius.

§start: f64

The angle it starts at, from the x axis.

§sweep: f64

The signed angle it turns through, less than a full turn.

Circle

A full circle, a whole outline on its own.

Fields

§centre: Point2

Its centre.

§radius: f64

Its radius.

§counter_clockwise: bool

Whether it runs counter-clockwise, as an outer boundary does.

Implementations§

impl Piece2

pub fn point_at(&self, t: f64) -> Point2

pub fn start(&self) -> Point2

Where it starts.

pub fn end(&self) -> Point2

Where it ends: where it starts, for a circle.

pub fn length(&self) -> f64

Its length.
