Struct draw::shape::LineBuilder

pub struct LineBuilder { /* fields omitted */ }

Helper object for building lines; provides a better syntax than building a Shape::Line from scratch.

Example

use draw::shape::LineBuilder;
use draw::{Position, Shape};
let mut line = LineBuilder::new(Position::new(0.0, 0.0));

line.line_to(Position{x: 50.0 ,y: 50.0 });
line.curve_to(Position::new(50.0, 50.0), Position::new(20.0, 30.0));

// Consume the builder, turn the line into a shape for use with the display list
let shape: Shape = line.into();

Methods

impl LineBuilder

pub fn new(start: Position) -> LineBuilder

Create a new LineBuilder with start as the origin

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

Draw a straight line to point

pub fn curve_to(&mut self, point: Position, curve: Position)

Draw a curve to point, with a single control point at curve

pub fn to_shape(self) -> Shape

Consume the LineBuilder, return a Shape::Line

Trait Implementations

impl From<LineBuilder> for Shape

fn from(line: LineBuilder) -> Shape

Performs the conversion.
