Struct Path 

pub struct Path {
    pub elements: Vec<PathEl>,
}

A vector path composed of a sequence of PathEl elements.

Paths are the primary geometric primitive passed to renderers. Use the builder methods (move_to, line_to, etc.) to construct paths incrementally, or the convenience constructors Path::rect and Path::circle for common shapes.

Fields

elements: Vec<PathEl>

The ordered sequence of path elements.

Implementations

impl Path

pub fn new() -> Self

Creates a new, empty path.

pub fn move_to(&mut self, x: f64, y: f64) -> &mut Self

Begins a new sub-path at (x, y).

pub fn line_to(&mut self, x: f64, y: f64) -> &mut Self

Appends a straight line from the current point to (x, y).

pub fn quad_to(&mut self, x1: f64, y1: f64, x: f64, y: f64) -> &mut Self

Appends a quadratic Bezier curve through control point (x1, y1) to endpoint (x, y).

pub fn curve_to( &mut self, x1: f64, y1: f64, x2: f64, y2: f64, x: f64, y: f64, ) -> &mut Self

Appends a cubic Bezier curve through control points (x1, y1) and (x2, y2) to endpoint (x, y).

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

Closes the current sub-path.

pub fn rect(r: Rect) -> Self

Creates a closed rectangular path from the given Rect.

pub fn circle(center: Point, radius: f64) -> Self

Creates a closed circular path centered at center with the given radius, approximated by four cubic Bezier curves.

The approximation uses the standard constant kappa ≈ 0.5522847498, which gives a maximum radial error of about 0.027%.

pub fn is_empty(&self) -> bool

Returns true if the path contains no elements.

Trait Implementations

impl Clone for Path

fn clone(&self) -> Path

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Path

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.
