Trait VectorMath

pub trait VectorMath: Sized {
    // Required methods
    fn dot(&self, other: &Self) -> f64;
    fn add(&self, other: &Self) -> Self;
    fn sub(&self, other: &Self) -> Self;
    fn mul(&self, scalar: f64) -> Self;
    fn mul_pt(&self, other: &Self) -> Self;

    // Provided methods
    fn norm(&self) -> f64 { ... }
    fn normalized(&self) -> Self { ... }
}

Treats object mathematically as if it were a vector.

Basically this is a way to perform math on objects like Vec<f64> without wrapping them in a struct.

Examples

Basic addition:

let a = vec![1.0f64, 1.0, 1.0];
let b = vec![1.0, 2.0, 3.0];
let c = a.add(&b);
assert_eq!(c, vec![2.0, 3.0, 4.0]);

Dot products:

let a = vec![1.0, 1.0, 1.0];
let b = vec![1.0, 0.0, 2.0];
assert_eq!(a.dot(b), 4.0);

Required Methods

fn dot(&self, other: &Self) -> f64

Computes dot product of two vectors.

fn add(&self, other: &Self) -> Self

Adds two vectors, returning a new vector.

fn sub(&self, other: &Self) -> Self

Subtracts two vectors, returning a new vector.

fn mul(&self, scalar: f64) -> Self

Multiplies a scalar and a vector, returning a new vector.

fn mul_pt(&self, other: &Self) -> Self

Multiplies a vector and a vector pointwise, returning a new vector.

Provided Methods

fn norm(&self) -> f64

Computes the vector norm

fn normalized(&self) -> Self

Normalizes the vector to unit length, returning a new vector

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
