Struct Vector 

pub struct Vector<const D: usize> { /* private fields */ }

Fixed-size vector of length D, stored inline.

Implementations

impl<const D: usize> Vector<D>

pub const fn new(data: [f64; D]) -> Self

Create a vector from a backing array.

Examples

use la_stack::prelude::*;

let v = Vector::<3>::new([1.0, 2.0, 3.0]);
assert_eq!(v.into_array(), [1.0, 2.0, 3.0]);

pub const fn zero() -> Self

All-zeros vector.

Examples

use la_stack::prelude::*;

let z = Vector::<2>::zero();
assert_eq!(z.into_array(), [0.0, 0.0]);

pub const fn as_array(&self) -> &[f64; D]

Borrow the backing array.

Examples

use la_stack::prelude::*;

let v = Vector::<2>::new([1.0, -2.0]);
assert_eq!(v.as_array(), &[1.0, -2.0]);

pub const fn into_array(self) -> [f64; D]

Consume and return the backing array.

Examples

use la_stack::prelude::*;

let v = Vector::<2>::new([1.0, 2.0]);
let a = v.into_array();
assert_eq!(a, [1.0, 2.0]);

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

Dot product.

Examples

use la_stack::prelude::*;

let a = Vector::<3>::new([1.0, 2.0, 3.0]);
let b = Vector::<3>::new([-2.0, 0.5, 4.0]);
assert!((a.dot(b) - 11.0).abs() <= 1e-12);

pub fn norm2_sq(self) -> f64

Squared Euclidean norm.

Examples

use la_stack::prelude::*;

let v = Vector::<3>::new([1.0, 2.0, 3.0]);
assert!((v.norm2_sq() - 14.0).abs() <= 1e-12);

Trait Implementations

impl<const D: usize> Clone for Vector<D>

fn clone(&self) -> Vector<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const D: usize> Debug for Vector<D>

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

Formats the value using the given formatter.

impl<const D: usize> Default for Vector<D>

fn default() -> Self

Returns the “default value” for a type.

impl<const D: usize> PartialEq for Vector<D>

fn eq(&self, other: &Vector<D>) -> 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.
