Struct Vector4

pub struct Vector4 { /* private fields */ }

A 4D vector. Wrapper around C++ implementation maliput::math::Vector4.

Example

use maliput::math::Vector4;

let v = Vector4::new(1.0, 2.0, 3.0, 4.0);
println!("v = {}", v);
assert_eq!(v.x(), 1.0);
assert_eq!(v.y(), 2.0);
assert_eq!(v.z(), 3.0);
assert_eq!(v.w(), 4.0);
assert_eq!(v.norm(), (1.0_f64.powi(2) + 2.0_f64.powi(2) + 3.0_f64.powi(2) + 4.0_f64.powi(2)).sqrt());

Implementations

impl Vector4

pub fn new(x: f64, y: f64, z: f64, w: f64) -> Vector4

Create a new Vector4 with the given x, y, z and w components.

pub fn x(&self) -> f64

Get the x component of the Vector4.

pub fn y(&self) -> f64

Get the y component of the Vector4.

pub fn z(&self) -> f64

Get the z component of the Vector4.

pub fn w(&self) -> f64

Get the w component of the Vector4.

pub fn norm(&self) -> f64

Get the norm of the Vector4.

pub fn dot(&self, w: &Vector4) -> f64

Get the dot product of the Vector4 with another Vector4.

pub fn normalize(&mut self)

Normalize the Vector4.

Trait Implementations

impl Debug for Vector4

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

Formats the value using the given formatter.

impl Display for Vector4

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

Formats the value using the given formatter.

impl PartialEq for Vector4

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