Struct Path 

pub struct Path { /* private fields */ }

A path built from lines and curves: Compose’s Path.

Example: a sparkline, stroked by crate::DrawScope::draw_path:

use cranpose_ui_graphics::{Path, Point};

let mut path = Path::new();
path.move_to(Point::new(0.0, 10.0));
path.line_to(Point::new(10.0, 4.0));
path.quadratic_to(Point::new(15.0, 0.0), Point::new(20.0, 6.0));
assert_eq!(path.contours().len(), 1);

Implementations

impl Path

pub fn new() -> Path

An empty path.

pub fn move_to(&mut self, point: Point)

Starts a new contour at point.

pub fn line_to(&mut self, point: Point)

Adds a straight edge from the pen to point.

pub fn quadratic_to(&mut self, control: Point, end: Point)

Adds the quadratic curve from the pen through control to end: Compose’s quadraticTo.

pub fn cubic_to(&mut self, first: Point, second: Point, end: Point)

Adds the cubic curve from the pen through first and second to end: Compose’s cubicTo.

pub fn close(&mut self)

Closes the current contour back to its first point; the next edge starts a new contour there.

pub fn reset(&mut self)

Removes every contour.

pub fn contours(&self) -> &[PathContour]

The contours, each flattened to points.

pub fn is_empty(&self) -> bool

Whether the path has no edge.

pub fn bounds(&self) -> Rect

The box of every point, or an empty rect at the origin for an empty path.

pub fn to_vector_path(&self, fill_rule: PathFillRule) -> VectorPath

The path as a fill: every contour closed, under fill_rule.

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<(), Error>

Formats the value using the given formatter.

impl Default for Path

fn default() -> Path

Returns the “default value” for a type.

impl PartialEq for Path

fn eq(&self, other: &Path) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
