Struct Vector2 

pub struct Vector2 {
    pub x: f64,
    pub y: f64,
}

A 2D vector.

Fields

x: f64

y: f64

Implementations

impl Vector2

pub const ZERO: Self

Zero vector.

pub fn new(x: f64, y: f64) -> Self

Creates a new vector.

pub fn length(&self) -> f64

Euclidean length.

pub fn length_sq(&self) -> f64

Squared length (avoids sqrt).

pub fn normalized(&self) -> Self

Returns a normalized (unit-length) vector, or zero vector if length is ~0.

pub fn cross(&self, other: &Self) -> f64

2D cross product (z-component of the 3D cross product).

Returns a positive value if other is counter-clockwise from self, negative if clockwise, zero if parallel.

pub fn dot(&self, other: &Self) -> f64

Dot product.

pub fn perp(&self) -> Self

Returns the perpendicular vector (rotated 90 degrees CCW).

Trait Implementations

impl Add<Vector2> for Point2

type Output = Point2

The resulting type after applying the + operator.

fn add(self, rhs: Vector2) -> Point2

Performs the + operation.

impl Add for Vector2

type Output = Vector2

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self

Performs the + operation.

impl Clone for Vector2

fn clone(&self) -> Vector2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vector2

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

Formats the value using the given formatter.

impl Mul<f64> for Vector2

type Output = Vector2

The resulting type after applying the * operator.

fn mul(self, rhs: f64) -> Self

Performs the * operation.

impl PartialEq for Vector2

fn eq(&self, other: &Vector2) -> 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 Sub for Vector2

type Output = Vector2

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self

Performs the - operation.

impl Copy for Vector2

impl StructuralPartialEq for Vector2
