Struct Vector2 

pub struct Vector2 {
    pub x: f64,
    pub y: f64,
}

A displacement or direction, distinct from a Point position.

Fields

x: f64

Horizontal displacement.

y: f64

Vertical displacement.

Implementations

impl Vector2

pub const ZERO: Self

A displacement with no movement.

pub const fn new(horizontal: f64, vertical: f64) -> Self

Preserves the supplied components; validation belongs to the consumer.

pub fn from_angle(radians: f64) -> Self

Returns a unit vector at clockwise radians from the positive horizontal axis. Principal quarter-turn angles preserve exact axis alignment.

pub fn length(self) -> f64

Returns Euclidean length without squaring unscaled components.

pub fn normalize(self) -> Self

Returns a unit direction, or zero for a zero vector. Finite very large or very small components are scaled before normalization. Nonfinite input does not become a finite zero vector.

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

Returns the scalar dot product.

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

Returns the signed two-dimensional cross product.

pub fn rotate(self, radians: f64) -> Self

Rotates clockwise in the downward-positive coordinate system.

pub fn interpolate(&self, target: &Self, progress: f64) -> Self

Linearly interpolates or extrapolates with double-precision progress.
