Struct PathShape 

pub struct PathShape(/* private fields */);

Immutable shared absolute path. Curves retain their controls for exact native fill; stroke length/reveal uses 32 equal-parameter segments per curve. Prepare paths once. Coordinates are bounded to ±1e9 logical pixels to keep native tessellation and length arithmetic in a useful finite range.

Implementations

impl PathShape

pub fn normalize_for_morph( &self, other: &Self, samples: usize, ) -> Result<(Self, Self), PathError>

Prepares equally sampled line topology for two paths. Subpaths match by order and must agree on open/closed status; winding and start points are preserved. This is geometric resampling, not semantic contour matching. Closed contours use samples points; open ones include both endpoints. Curves retain the measurement’s documented approximation. Cache the result before constructing PathMorphState so no conversion happens per frame.

Errors

Returns Topology for different contour counts/closure, Geometry for zero-length contours, or Complexity outside 2..=4096 samples or above 65,536 total output points per shape.

impl PathShape

pub fn parse_svg(data: &str) -> Result<Self, SvgPathError>

Parses an SVG d string, resolving relative/implicit/smooth commands and converting elliptical arcs to cubic Beziers. This does not parse an SVG document, paints, transforms, or CSS. Prepare once outside rendering. Input is bounded to 1 MiB and 65,536 expanded commands.

Errors

Returns grammar errors with their original position, geometry errors for non-finite/out-of-range coordinates, or Complexity when budgets are exceeded.

use gpui_ce_motion::PathShape;
let path = PathShape::parse_svg("M0 0h20a10 10 0 0 1 10 10z").unwrap();
assert!(path.commands().len() >= 4);

impl PathShape

pub fn new( commands: impl IntoIterator<Item = PathCommand>, ) -> Result<Self, PathError>

Validates commands before allocating retained morph state.

pub fn commands(&self) -> &[PathCommand]

Prepared absolute commands.

pub fn compatible(&self, other: &Self) -> bool

Whether native coordinate interpolation can preserve command topology.
