What belongs here

use-vector owns plain f64 vector primitives and reusable vector operations. The current surface includes Vector2, Vector3, Vector4, dot products, Vector3::cross, norms, normalization, scaling, distances, and linear interpolation.

Scalar division follows normal f64 semantics. Dividing by zero yields infinities or NaN instead of panicking.

Neighboring crates

Crate	Responsibility
`use-vector`	Vector primitives and vector operations
`use-matrix`	Matrix primitives
`use-linear`	Higher-level linear algebra algorithms and matrix-oriented workflows
`use-geometry`	Points, shapes, angles, geometric relationships, and spatial algorithms
`use-physics`	Physical formulas that use vectors

use-vector intentionally does not add geometry-specific types, matrices, unit-aware vectors, or domain-specific physics helpers.

Examples

Vector magnitude

use use_vector::Vector2;

let a = Vector2::new(3.0, 4.0);

assert_eq!(a.magnitude(), 5.0);

Dot and cross products

use use_vector::{Vector2, Vector3};

let a = Vector2::new(1.0, 2.0);
let b = Vector2::new(3.0, 4.0);

assert_eq!(a.dot(b), 11.0);

let x = Vector3::new(1.0, 0.0, 0.0);
let y = Vector3::new(0.0, 1.0, 0.0);

assert_eq!(x.cross(y), Vector3::new(0.0, 0.0, 1.0));

Normalization

use use_vector::Vector2;

let unit = Vector2::new(3.0, 4.0)
    .normalize()
    .expect("non-zero finite vector should normalize");

assert!((unit.x - 0.6).abs() < 1.0e-12);
assert!((unit.y - 0.8).abs() < 1.0e-12);

Distance

use use_vector::Vector3;

let start = Vector3::ZERO;
let end = Vector3::new(2.0, 3.0, 6.0);

assert_eq!(start.distance(end), 7.0);

Status

use-vector is a concrete pre-1.0 crate in the RustUse math workspace. The API stays small, explicit, and dependency-free so adjacent crates can build on a stable vector core.
