pub fn as_array(&self) -> [f32; 2]

pub const fn from_array(v: [f32; 2]) -> Self

Crée un vecteur depuis un tableau [x, y].

pub fn dot(&self, rhs: &Self) -> f32

Produit scalaire : self · rhs = x₁x₂ + y₁y₂.

pub fn norm_sq(&self) -> f32

Norme au carré : x² + y². Infaillible.

pub fn norm(&self) -> Result<f32, VecError>

Retourne VecError::NonFiniteValue si un composant est NaN ou infini.

pub fn normalize(&self) -> Result<Self, VecError>

Vecteur unitaire dans la même direction.

Retourne VecError::ZeroNorm si la norme est nulle. Retourne VecError::NonFiniteValue si un composant est invalide.

pub fn distance(&self, rhs: &Self) -> Result<f32, VecError>

Distance entre deux vecteurs.

pub fn lerp(&self, rhs: &Self, t: f32) -> Self

Interpolation linéaire : self + t * (rhs - self), t ∈ [0, 1].

pub fn hadamard(&self, rhs: &Self) -> Self

Multiplication terme à terme (produit de Hadamard).

pub fn is_finite(&self) -> bool

Retourne true si tous les composants sont finis (non NaN, non infini).

Trait Implementations

impl Add for Vec2

type Output = Vec2

The resulting type after applying the + operator.

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Debug for Vec2

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

Formats the value using the given formatter.

impl Div<f32> for Vec2

type Output = Vec2

The resulting type after applying the / operator.
