Struct PathBuilder 

pub struct PathBuilder { /* private fields */ }

Imperative builder for a single VectorPath. Mirrors a subset of the SVG path command vocabulary (M, L, C, Q, Z) plus fill/stroke style. Returns a VectorPath; combine multiple via VectorAsset::from_paths.

use aetna_core::vector::{
    PathBuilder, VectorAsset, VectorColor, VectorLineCap,
};
use aetna_core::tree::Color;

let curve = PathBuilder::new()
    .move_to(0.0, 0.0)
    .cubic_to(20.0, 0.0, 0.0, 60.0, 20.0, 60.0)
    .stroke_solid(Color::rgb(80, 200, 240), 2.0)
    .stroke_line_cap(VectorLineCap::Round)
    .build();
let asset = VectorAsset::from_paths([0.0, 0.0, 20.0, 60.0], vec![curve]);
// `asset.content_hash()` is stable across rebuilds with the same inputs,
// so backends share one atlas slot per unique geometry.

Implementations

impl PathBuilder

pub fn new() -> Self

pub fn move_to(self, x: f32, y: f32) -> Self

SVG M x y.

pub fn line_to(self, x: f32, y: f32) -> Self

SVG L x y.

pub fn quad_to(self, cx: f32, cy: f32, x: f32, y: f32) -> Self

SVG Q cx cy x y.

pub fn cubic_to( self, c1x: f32, c1y: f32, c2x: f32, c2y: f32, x: f32, y: f32, ) -> Self

SVG C c1x c1y c2x c2y x y.

pub fn close(self) -> Self

SVG Z — close the current subpath back to its MoveTo.

pub fn fill_solid(self, color: Color) -> Self

Fill with a solid colour at full opacity, non-zero rule. For finer control set Self::fill directly.

pub fn fill(self, fill: Option<VectorFill>) -> Self

Set the fill explicitly. None clears it.

pub fn stroke_solid(self, color: Color, width: f32) -> Self

Stroke with a solid colour and explicit width, with default line cap (Butt), line join (Miter), and miter limit (4.0). For finer control chain Self::stroke_line_cap / Self::stroke_line_join / Self::stroke_miter_limit.

pub fn stroke(self, stroke: Option<VectorStroke>) -> Self

Set the stroke explicitly. None clears it.

pub fn stroke_line_cap(self, cap: VectorLineCap) -> Self

pub fn stroke_line_join(self, join: VectorLineJoin) -> Self

pub fn stroke_miter_limit(self, limit: f32) -> Self

pub fn stroke_opacity(self, opacity: f32) -> Self

pub fn build(self) -> VectorPath

impl Default for PathBuilder

fn default() -> Self

Returns the “default value” for a type.
