Struct Vec2 

pub struct Vec2 {
    pub dx: f64,
    pub dy: f64,
}

A 2D vector (displacement) in logical pixels.

Distinct from Point: a Vec2 is a difference between points, not a position. Subtracting two points yields a Vec2; adding a Vec2 to a point yields a point.

Fields

dx: f64

dy: f64

Implementations

impl Vec2

pub const ZERO: Self

pub const fn new(dx: f64, dy: f64) -> Self

pub const fn splat(v: f64) -> Self

Uniform vector with both components set to v.

pub fn length(self) -> f64

pub fn length_squared(self) -> f64

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

pub fn normalized(self) -> Self

Returns the unit vector in the same direction, or Vec2::ZERO if the length is zero.

Trait Implementations

impl Add for Vec2

type Output = Vec2

The resulting type after applying the + operator.

fn add(self, rhs: Vec2) -> Vec2

Performs the + operation.

impl Add<Vec2> for Point

type Output = Point

The resulting type after applying the + operator.

fn add(self, rhs: Vec2) -> Point

Performs the + operation.

impl Clone for Vec2

fn clone(&self) -> Vec2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Vec2

impl Debug for Vec2

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

Formats the value using the given formatter.

impl Default for Vec2

fn default() -> Vec2

Returns the “default value” for a type.

impl Div<f64> for Vec2

type Output = Vec2

The resulting type after applying the / operator.

fn div(self, rhs: f64) -> Vec2

Performs the / operation.

impl Mul<f64> for Vec2

type Output = Vec2

The resulting type after applying the * operator.

fn mul(self, rhs: f64) -> Vec2

Performs the * operation.

impl Neg for Vec2

type Output = Vec2

The resulting type after applying the - operator.

fn neg(self) -> Vec2

Performs the unary - operation.

impl PartialEq for Vec2

fn eq(&self, other: &Vec2) -> 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 StructuralPartialEq for Vec2

impl Sub for Vec2

type Output = Vec2

The resulting type after applying the - operator.

fn sub(self, rhs: Vec2) -> Vec2

Performs the - operation.

impl Sub<Vec2> for Point

type Output = Point

The resulting type after applying the - operator.

fn sub(self, rhs: Vec2) -> Point

Performs the - operation.
