Struct box2d_rs::b2_math::B2vec2

pub struct B2vec2 {
    pub x: f32,
    pub y: f32,
}

A 2D column vector.

Fields

x: f32

y: f32

Implementations

impl B2vec2

pub fn new(x_in: f32, y_in: f32) -> B2vec2

Construct using coordinates.

pub fn zero() -> B2vec2

pub fn set_zero(&mut self)

Set this vector to all zeros.

pub fn set(&mut self, x_: f32, y_: f32)

Set this vector to some specified coordinates.

pub fn get(self, i: i32) -> f32

pub fn set_by_index(&mut self, i: i32, value: f32)

pub fn length(self) -> f32

Get the length of this vector (the norm).

pub fn length_squared(self) -> f32

Get the length squared. For performance, use this instead of B2vec2::length (if possible).

pub fn normalize(&mut self) -> f32

Convert this vector into a unit vector. Returns the length.

pub fn is_valid(self) -> bool

Does this vector contain finite coordinates?

pub fn skew(self) -> B2vec2

Get the skew vector such that dot(skew_vec, other) == cross(vec, other)

Trait Implementations

impl Add<B2vec2> for B2vec2

fn add(self, b: B2vec2) -> B2vec2

Add two vectors component-wise.

type Output = B2vec2

The resulting type after applying the + operator.

impl AddAssign<B2vec2> for B2vec2

fn add_assign(&mut self, other: B2vec2)

Add a vector to this vector.

impl Clone for B2vec2

fn clone(&self) -> B2vec2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for B2vec2

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

Formats the value using the given formatter.

impl Default for B2vec2

fn default() -> B2vec2

Returns the “default value” for a type.

impl Mul<B2vec2> for f32

type Output = B2vec2

The resulting type after applying the * operator.

fn mul(self, a: B2vec2) -> B2vec2

Performs the * operation.

impl MulAssign<f32> for B2vec2

fn mul_assign(&mut self, other: f32)

Multiply this vector by a scalar.

impl Neg for B2vec2

fn neg(self) -> B2vec2

Negate this vector.

type Output = B2vec2

The resulting type after applying the - operator.

impl PartialEq<B2vec2> for B2vec2

fn eq(&self, other: &B2vec2) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub<B2vec2> for B2vec2

fn sub(self, b: B2vec2) -> B2vec2

Subtract two vectors component-wise.

type Output = B2vec2

The resulting type after applying the - operator.

impl SubAssign<B2vec2> for B2vec2

fn sub_assign(&mut self, other: B2vec2)

Subtract a vector from this vector.

impl Copy for B2vec2

impl StructuralPartialEq for B2vec2
