Core trait for building path objects in vector graphics.

Required Methods

fn current(&self) -> Point

Returns the current position in the path.

fn move_to_impl(&mut self, to: Point) -> &mut Self

fn line_to_impl(&mut self, to: Point) -> &mut Self

fn quadratic_to_impl(&mut self, c1: Point, to: Point) -> &mut Self

fn cubic_to_impl(&mut self, c1: Point, c2: Point, to: Point) -> &mut Self

fn close(&mut self) -> &mut Self

Closes the current sub-path by drawing a straight line back to the starting point.

Provided Methods

fn move_to(&mut self, to: impl Into<Point>) -> &mut Self

Moves the current position to the specified point.

fn line_to(&mut self, to: impl Into<Point>) -> &mut Self

Draws a straight line from the current position to the specified point.

fn quadratic_to( &mut self, c1: impl Into<Point>, to: impl Into<Point>, ) -> &mut Self

Draws a quadratic Bézier curve from the current position to the specified point with the given control point.

fn cubic_to( &mut self, c1: impl Into<Point>, c2: impl Into<Point>, to: impl Into<Point>, ) -> &mut Self

Draws a cubic Bézier curve from the current position to the specified point with the given control points.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
