Struct nannou::geom::path::Builder

pub struct Builder { /* fields omitted */ }

A type used for building a 2D lyon path.

Implementations

impl Builder

pub fn new() -> Self

Begin building a new path.

pub fn with_capacity(points: usize, edges: usize) -> Self

Build a path with the given capacity for the inner path event storage.

pub fn with_svg(self) -> SvgPathBuilder<Self>

Returns a lyon builder that supports SVG commands.

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

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

pub fn move_to(self, to: Point2) -> Self

Sets the position in preparation for the next sub-path.

If the current sub-path contains edges, this ends the sub-path without closing it.

pub fn line_to(self, to: Point2) -> Self

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

pub fn close(self) -> Self

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

pub fn quadratic_bezier_to(self, ctrl: Point2, to: Point2) -> Self

Add a quadratic bezier curve to the path.

pub fn cubic_bezier_to(self, ctrl1: Point2, ctrl2: Point2, to: Point2) -> Self

Add a cubic bezier curve to the path.

pub fn arc(
    self,
    center: Point2,
    radii: Vector2,
    sweep_angle_radians: f32,
    x_rotation_radians: f32
) -> Self

Add an arc to the path.

pub fn polygon(self, points: &[Point2]) -> Self

Add a closed polygon.

pub fn position(&self) -> Point2

Returns the current position of the head of the path.

pub fn build(self) -> Path

Build the path and return it.

pub fn inner(&self) -> &Builder

Access to the inner lyon::path::Builder.

pub fn inner_mut(&mut self) -> &mut Builder

Mutable access to the inner lyon::path::Builder.

Trait Implementations

impl Build for Builder

type PathType = Path

The type of object that is created by this builder.

fn build(self) -> Self::PathType

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

fn build_and_reset(&mut self) -> Self::PathType

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

impl FlatPathBuilder for Builder

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

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

impl From<Builder> for Builder

fn from(builder: Builder) -> Self

Performs the conversion.

impl Into<Builder> for Builder

fn into(self) -> Builder

Performs the conversion.

impl PathBuilder for Builder

    sweep_angle: Angle,
    x_rotation: Angle
)

fn path_event(&mut self, event: PathEvent)

fn with_svg(self) -> SvgPathBuilder<Self>
