pub struct Arc { /* private fields */ }

An Arc is a portion of the circumference of a circle.

Implementations

impl Arc

pub fn new( center: Point2D, radius: f32, start_angle: f32, end_angle: f32, ) -> Arc

Creates a new Arc object from a center point, radius, start angle, and end angle.

pub fn vector_object_builder( &self, samples: Option<usize>, ) -> VectorObjectBuilder

Creates a new vector object builder with the arc’s points.

pub fn center(&self) -> Point2D

Returns the center point of the arc.

pub fn radius(&self) -> f32

Returns the radius of the arc.

pub fn start_angle(&self) -> f32

Returns the start angle of the arc in radians.

pub fn end_angle(&self) -> f32

Returns the end angle of the arc in radians.

pub fn start_tip_vector_object_builder( &self, tip_shape: VectorObjectBuilder, samples: Option<usize>, ) -> VectorObjectBuilder

Returns a VectorObjectBuilder representing the arc and a tip at the start of the arc.

pub fn end_tip_vector_object_builder( &self, tip_shape: VectorObjectBuilder, samples: Option<usize>, ) -> VectorObjectBuilder

Returns a VectorObjectBuilder representing the arc and a tip at the end of the arc.

pub fn both_tips_vector_object_builder( &self, tip_shape: VectorObjectBuilder, samples: Option<usize>, ) -> VectorObjectBuilder

Returns a VectorObjectBuilder representing the arc and tips at both ends of the arc.

pub fn point_at(&self, t: f32) -> Point2D

Returns the point on the arc at a given t progress value.

pub fn length(&self) -> f32

Returns the length of the arc.

Trait Implementations

impl Clone for Arc

fn clone(&self) -> Arc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Arc

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

Formats the value using the given formatter.

impl From<Arc> for JsValue

fn from(value: Arc) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Arc

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Arc

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for Arc

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Arc>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Arc

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Arc

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for Arc

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Arc>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Arc

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Arc>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl Tipable for Arc

fn start(&self) -> Point2D

fn tip_at_start(&self, shape: VectorObjectBuilder) -> VectorObjectBuilder

impl TryFromJsValue for Arc

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>

Performs the conversion.
