Struct Line 

pub struct Line {
    pub start: Point2D,
    pub end: Point2D,
}

A Line is a straight one-dimensional figure that extends infinitely in both directions. It is defined by two points.

Fields

start: Point2D

The starting point of the line as Point2D.

end: Point2D

The ending point of the line as Point2D.

Implementations

impl Line

pub fn new(start: Point2D, end: Point2D) -> Line

Creates a new Line object from two points.

pub fn vector_object_builder(&self) -> VectorObjectBuilder

Gets a VectorObjectBuilder with the line’s points.

pub fn length(&self) -> f32

Returns the length of the line.

pub fn midpoint(&self) -> Point2D

Returns the midpoint of the line as a Point2D.

pub fn slope(&self) -> f32

Returns the slope of the line.

pub fn y_intercept(&self) -> f32

Returns the y-intercept of the line.

pub fn normal_slope(&self) -> f32

Returns the normal slope of the line.

pub fn perpendicular_line(&self, point: Point2D) -> Line

Returns the perpendicular line of the line at a given Point2D.

pub fn intersection(&self, other: &Line) -> Option<Point2D>

Returns the intersection Point2D of the line with another line, if it exists.

pub fn contains(&self, point: Point2D) -> bool

Returns whether the line contains a given Point2D.

pub fn distance_to_point(&self, point: Point2D) -> f32

Returns the distance from the line to a given Point2D.

pub fn with_tip_at_the_start( &self, tip_shape: VectorObjectBuilder, ) -> VectorObjectBuilder

Creates a VectorObjectBuilder with the line’s points and a tip at the start.

pub fn with_tip_at_the_end( &self, tip_shape: VectorObjectBuilder, ) -> VectorObjectBuilder

Creates a VectorObjectBuilder with the line’s points and a tip at the end.

pub fn with_tips_at_both_ends( &self, tip_shape: VectorObjectBuilder, ) -> VectorObjectBuilder

Creates a VectorObjectBuilder with the line’s points and tips at both ends.

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Line

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

Formats the value using the given formatter.

impl From<Line> for JsValue

fn from(value: Line) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Line

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 Line

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 Line

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Line>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Line

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 Line

fn none() -> Self::Abi

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

impl PartialEq for Line

fn eq(&self, other: &Line) -> 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.

impl RefFromWasmAbi for Line

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Line>

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 Line

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Line>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl Tipable for Line
