pub const fn unit_x() -> Self

Returns a vector of (1.0, 0.0, 0.0).

pub const fn unit_y() -> Self

Returns a vector of (0.0, 1.0).

pub fn dot(&self, rhs: &Vector2) -> Scalar

Trait Implementations

impl AbsDiffEq for Vector2

type Epsilon = f32

Used for specifying relative comparisons.

fn default_epsilon() -> Self::Epsilon

The default tolerance to use when testing values that are close together.

fn abs_diff_eq(&self, other: &Self, epsilon: Self::Epsilon) -> bool

A test for equality that uses the absolute difference to compute the approximate equality of two numbers.

fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool

The inverse of ApproxEq::abs_diff_eq.

impl Add for Vector2

type Output = Vector2

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign for Vector2

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

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 Default for Vector2

fn default() -> Vector2

Returns the “default value” for a type.

impl Div<f32> for Vector2

type Output = Vector2

The resulting type after applying the / operator.

fn div(self, rhs: Scalar) -> Self::Output

Performs the / operation.

impl DivAssign<f32> for Vector2
