Struct Vec2 

#[repr(C)]
pub struct Vec2 {
    pub x: f64,
    pub y: f64,
}

A 2D vector. Derived from kurbo.

This is intended primarily for a vector in the mathematical sense, but it can be interpreted as a translation, and converted to and from a point (vector relative to the origin) and size.

Fields

x: f64

The x-coordinate.

y: f64

The y-coordinate.

Implementations

impl Vec2

pub const ZERO: Vec2

The vector (0, 0).

pub const fn new(x: f64, y: f64) -> Vec2

Create a new vector.

pub const fn to_point(self) -> Point

Convert this vector into a Point.

pub const fn to_size(self) -> Size

Convert this vector into a Size.

Trait Implementations

impl Add for Vec2

type Output = Vec2

The resulting type after applying the + operator.

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

Performs the + operation.

impl Add<Vec2> for Point

type Output = Point

The resulting type after applying the + operator.

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

Performs the + operation.

impl Add<Vec2> for Rect

type Output = Rect

The resulting type after applying the + operator.

fn add(self, v: Vec2) -> Rect

Performs the + operation.

impl AddAssign for Vec2

fn add_assign(&mut self, other: Vec2)

Performs the += operation.

impl AddAssign<Vec2> for Point

fn add_assign(&mut self, other: Vec2)

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<(), Error>

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

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

Note: division by a scalar is implemented by multiplying by the reciprocal.

This is more efficient but has different roundoff behavior than division.

type Output = Vec2

The resulting type after applying the / operator.

impl DivAssign<f64> for Vec2

fn div_assign(&mut self, other: f64)

Performs the /= operation.

impl From<(f64, f64)> for Vec2

fn from(v: (f64, f64)) -> Vec2

Converts to this type from the input type.

impl Mul<f64> for Vec2

type Output = Vec2

The resulting type after applying the * operator.

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

Performs the * operation.

impl MulAssign<f64> for Vec2

fn mul_assign(&mut self, other: f64)

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Vec2

impl Sub for Vec2

type Output = Vec2

The resulting type after applying the - operator.

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

Performs the - operation.

impl Sub<Vec2> for Point

type Output = Point

The resulting type after applying the - operator.

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

Performs the - operation.

impl Sub<Vec2> for Rect

type Output = Rect

The resulting type after applying the - operator.

fn sub(self, v: Vec2) -> Rect

Performs the - operation.

impl SubAssign for Vec2

fn sub_assign(&mut self, other: Vec2)

Performs the -= operation.

impl SubAssign<Vec2> for Point

fn sub_assign(&mut self, other: Vec2)

Performs the -= operation.
