Struct Curve

pub struct Curve { /* private fields */ }

A bezier curve.

Implementations

impl Curve

pub fn new() -> Curve

Create a new curve.

pub fn rect(rect: Rect) -> Curve

Create a curve from a rectangle.

pub fn ellipse(oval: Rect) -> Curve

Create a curve from an oval.

pub fn circle(center: Point, radius: f32) -> Curve

Create a curve from a cicrle.

pub fn get_hash(&self) -> u64

Get the hash of the curve.

This is a non-cryptographic fast hash, and is cached.

pub fn len(&self) -> usize

Get the number of verbs in the curve.

pub fn is_empty(&self) -> bool

Check if the curve is empty.

pub fn is_valid(&self) -> bool

Check if the curve is valid.

pub fn is_closed(&self) -> bool

Check if the curve is closed.

pub fn bounds(&self) -> Rect

Get the bounds of the curve.

pub fn clear(&mut self)

Clear the curve, retaining the allocated memory for reuse.

pub fn points(&self) -> &[Point]

Get the points in the curve.

pub fn verbs(&self) -> &[CurveVerb]

Get the verbs in the curve.

pub fn last_point(&self) -> Option<Point>

Get the last point in the curve.

pub fn move_to(&mut self, point: Point)

Move to a point.

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

Draw a line to a point.

pub fn quad_to(&mut self, control: Point, point: Point)

Draw a quadratic bezier curve to a point, with a control point control.

pub fn cubic_to(&mut self, a: Point, b: Point, point: Point)

Draw a cubic bezier curve to a point, with control points a and b.

pub fn conic_to(&mut self, control: Point, point: Point, weight: f32)

Draw a conic curve to a point, with a control point control and a weight.

Conic curves are approximated by quadratic bezier curves.

pub fn close(&mut self)

Close the contour.

pub fn transform(&mut self, transform: Affine)

Transform the curve by the given affine transform.

pub fn iter(&self) -> CurveIter<'_>

Get an iterator over the curve segments.

pub fn contains(&self, point: Point, rule: FillRule) -> bool

Check if the curve contains a point using the given rule.

pub fn stroke_curve(&mut self, curve: &Curve, stroke: Stroke)

Stroke the curve with the given stroke.

pub fn push_rect(&mut self, rect: Rect)

Push a rectangle to the curve.

pub fn push_oval(&mut self, oval: Rect)

Push an oval to the curve.

pub fn push_rect_with_radius(&mut self, rect: Rect, radius: BorderRadius)

Push a rectangle with rounded corners to the curve.

pub fn push_rect_with_borders( &mut self, rect: Rect, radius: BorderRadius, width: BorderWidth, )

Push the border of a rectangle with rounded corners to the curve.

Trait Implementations

impl Clone for Curve

fn clone(&self) -> Curve

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Curve

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Curve

fn default() -> Curve

Returns the “default value” for a type.

impl From<Rect> for Curve

fn from(rect: Rect) -> Curve

Converts to this type from the input type.

impl Hash for Curve

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a Curve

type Item = CurveSegment

The type of the elements being iterated over.

type IntoIter = CurveIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <&'a Curve as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for Curve

fn eq(&self, other: &Curve) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
