Implementations

impl FourVector

pub fn new(t: f64, x: f64, y: f64, z: f64) -> Self

pub fn zero() -> Self

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

Minkowski dot product with signature (+, -, -, -).

pub fn norm_sq(&self) -> f64

Minkowski norm squared (invariant interval).

pub fn norm(&self) -> f64

Minkowski norm. Returns NaN for spacelike vectors if you take sqrt of negative.

pub fn spatial(&self) -> Vec3

Spatial part as a Vec3.

pub fn spatial_magnitude(&self) -> f64

Spatial magnitude.

pub fn boost(&self, velocity: Vec3, c: f64) -> FourVector

Apply a Lorentz boost along an arbitrary direction.

pub fn scale(&self, s: f64) -> FourVector

Scale by a scalar.

pub fn add(&self, other: &FourVector) -> FourVector

Add two four-vectors.

pub fn sub(&self, other: &FourVector) -> FourVector

Subtract another four-vector.

Trait Implementations

impl Add for FourVector

type Output = FourVector

The resulting type after applying the + operator.

fn add(self, rhs: FourVector) -> FourVector

Performs the + operation.

impl Clone for FourVector

fn clone(&self) -> FourVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FourVector

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

Formats the value using the given formatter.

impl Mul<f64> for FourVector

type Output = FourVector

The resulting type after applying the * operator.

fn mul(self, rhs: f64) -> FourVector

Performs the * operation.

impl Neg for FourVector

type Output = FourVector

The resulting type after applying the - operator.

fn neg(self) -> FourVector

Performs the unary - operation.

impl PartialEq for FourVector

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

impl Sub for FourVector

type Output = FourVector

The resulting type after applying the - operator.

fn sub(self, rhs: FourVector) -> FourVector

Performs the - operation.

impl Copy for FourVector

impl StructuralPartialEq for FourVector
