Implementations

impl Vector

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

Create a new vector

pub fn x(&self) -> f64

Get the x value

pub fn y(&self) -> f64

Get the y value

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

pub fn negate(&mut self)

Negate the vector, negating each of the components

pub fn magnitude(&self) -> f64

Get the length (magnitude) of the vector

pub fn normalise(&mut self)

Normalise the vector

Trait Implementations

impl<'a, 'b> Add<&'b Position> for &'a Vector

type Output = Position

The resulting type after applying the + operator.

fn add(self, other: &'b Position) -> Position

Performs the + operation.

impl<'a, 'b> Add<&'b Vector> for &'a Position

type Output = Position

The resulting type after applying the + operator.

fn add(self, other: &'b Vector) -> Position

impl<'a, 'b> Add<&'b Vector> for &'a Vector

type Output = Vector

The resulting type after applying the + operator.

fn add(self, other: &'b Vector) -> Vector

Performs the + operation.

impl Add for Vector

type Output = Vector

The resulting type after applying the + operator.

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

Performs the + operation.

impl<'a> AddAssign<&'a Vector> for Vector

fn add_assign(&mut self, other: &Self)

Performs the += operation.

impl AddAssign for Vector

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Debug for Vector

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

Formats the value using the given formatter.

impl Mul<Vector> for f64

type Output = Vector

The resulting type after applying the * operator.

fn mul(self, vector: Vector) -> Vector

Performs the * operation.

impl Mul<f64> for Vector

type Output = Vector

The resulting type after applying the * operator.

fn mul(self, scalar: f64) -> Vector

Performs the * operation.

impl PartialEq for Vector

fn eq(&self, other: &Vector) -> 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 Vector

type Output = Vector

The resulting type after applying the - operator.

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

Performs the - operation.

impl SubAssign for Vector

fn sub_assign(&mut self, other: Self)

Performs the -= operation.
