Type Definition munum::Vec4

pub type Vec4<T = f32> = Vector<T, 4>;

A 4D vector

Implementations

impl<T: Copy + NumAssign> Vec4<T>

pub fn from_vec3(v: Vec3<T>, w: T) -> Self

Creates a new Vec4 from a Vec3 and w component.

Examples

let v = Vec3::<i32>::from_slice(&[2, 3, 4]);
assert_eq!(*Vec4::<i32>::from_vec3(v, 1).as_ref(), [2, 3, 4, 1]);

pub fn xy(&self) -> Vec2<T>

Returns a copy of the xy components as a Vec2.

Examples

let v = Vec4::<i32>::from_slice(&[1, 2, 3, 4]);
assert_eq!(*v.xy().as_ref(), [1, 2]);

pub fn xyz(&self) -> Vec3<T>

Returns a copy of the xyz components as a Vec3.

Examples

let v = Vec4::<i32>::from_slice(&[1, 2, 3, 4]);
assert_eq!(*v.xyz().as_ref(), [1, 2, 3]);
