Struct Vec4 

#[repr(C)]
pub struct Vec4 {
    pub x: f32,
    pub y: f32,
    pub z: f32,
    pub w: f32,
}

A 4D vector with FFI-safe memory layout.

This type is commonly used for homogeneous coordinates in graphics or RGBA colors. It is guaranteed to have the same memory layout as a C struct with four consecutive f32 fields.

Fields

x: f32

The x-component of the vector.

y: f32

The y-component of the vector.

z: f32

The z-component of the vector.

w: f32

The w-component of the vector.

Implementations

impl Vec4

pub const fn new(x: f32, y: f32, z: f32, w: f32) -> Vec4

Creates a new Vec4 from x, y, z, w components.

pub const fn zero() -> Vec4

Returns the zero vector (0, 0, 0, 0).

pub const fn one() -> Vec4

Returns the one vector (1, 1, 1, 1).

pub const fn from_vec3(v: Vec3, w: f32) -> Vec4

Creates a Vec4 from a Vec3 and w component.

pub const fn xyz(self) -> Vec3

Returns the xyz components as a Vec3.

pub fn dot(self, other: Vec4) -> f32

Computes the dot product of two vectors.

pub fn length_squared(self) -> f32

Returns the squared length of the vector.

pub fn length(self) -> f32

Returns the length (magnitude) of the vector.

pub fn normalize(self) -> Vec4

Returns a normalized (unit length) version of this vector.

pub fn lerp(self, other: Vec4, t: f32) -> Vec4

Linearly interpolates between two vectors.

Trait Implementations

impl Add for Vec4

type Output = Vec4

The resulting type after applying the + operator.

fn add(self, other: Vec4) -> Vec4

Performs the + operation.

impl Clone for Vec4

fn clone(&self) -> Vec4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vec4

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

Formats the value using the given formatter.

impl Default for Vec4

fn default() -> Vec4

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Vec4

fn deserialize<__D>( __deserializer: __D, ) -> Result<Vec4, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Div<f32> for Vec4

type Output = Vec4

The resulting type after applying the / operator.

fn div(self, scalar: f32) -> Vec4

Performs the / operation.

impl From<Vector4<f32>> for Vec4

fn from(v: Vector4<f32>) -> Vec4

Converts to this type from the input type.

impl Mul<f32> for Vec4

type Output = Vec4

The resulting type after applying the * operator.

fn mul(self, scalar: f32) -> Vec4

Performs the * operation.

impl Neg for Vec4

type Output = Vec4

The resulting type after applying the - operator.

fn neg(self) -> Vec4

Performs the unary - operation.

impl PartialEq for Vec4

fn eq(&self, other: &Vec4) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub for Vec4

type Output = Vec4

The resulting type after applying the - operator.

fn sub(self, other: Vec4) -> Vec4

Performs the - operation.

impl Copy for Vec4

impl StructuralPartialEq for Vec4
