Struct lyon_tessellation::StrokeBuilder

pub struct StrokeBuilder<'l> { /* fields omitted */ }

A builder that tessellates a stroke directly without allocating any intermediate data structure.

Methods

impl<'l> StrokeBuilder<'l>

pub fn new(
    options: &StrokeOptions,
    builder: &'l mut dyn GeometryBuilder<Vertex>
) -> Self

pub fn set_options(&mut self, options: &StrokeOptions)

Trait Implementations

impl<'l> PathBuilder for StrokeBuilder<'l>

fn quadratic_bezier_to(&mut self, ctrl: Point, to: Point)

fn cubic_bezier_to(&mut self, ctrl1: Point, ctrl2: Point, to: Point)

fn arc(
    &mut self,
    center: Point,
    radii: Vector,
    sweep_angle: Angle,
    x_rotation: Angle
)

fn path_event(&mut self, event: PathEvent)

fn with_svg(self) -> SvgPathBuilder<Self>

Returns a builder that support svg commands.

impl<'l> FlatPathBuilder for StrokeBuilder<'l>

fn move_to(&mut self, to: Point)

Sets the current position in preparation for the next sub-path. If the current sub-path contains edges, this ends the sub-path without closing it.

fn line_to(&mut self, to: Point)

Adds a line segment to the current sub-path and set the current position.

fn close(&mut self)

Closes the current sub path and sets the current position to the first position of this the current sub-path.

fn current_position(&self) -> Point

fn flat_event(&mut self, event: FlattenedEvent)

fn flattened(self, tolerance: f32) -> FlatteningBuilder<Self>

Returns a builder that approximates all curves with sequences of line segments.

impl<'l> Build for StrokeBuilder<'l>

type PathType = Result<(), GeometryBuilderError>

The type of object that is created by this builder.

fn build(self) -> Result<(), GeometryBuilderError>

Builds a path object and resets the builder so that it can be used again.

fn build_and_reset(&mut self) -> Result<(), GeometryBuilderError>

Builds a path object and resets the builder so that it can be used again.
