Struct Vec2 

#[repr(C)]
pub struct Vec2 {
    pub x: f32,
    pub y: f32,
}

A 2D vector with FFI-safe memory layout.

This type is guaranteed to have the same memory layout as a C struct with two consecutive f32 fields. Use this type for any 2D positions, velocities, or texture coordinates that cross FFI boundaries.

Fields

x: f32

The x-component of the vector.

y: f32

The y-component of the vector.

Implementations

impl Vec2

pub const fn new(x: f32, y: f32) -> Vec2

Creates a new Vec2 from x and y components.

pub const fn zero() -> Vec2

Returns the zero vector (0, 0).

pub const fn one() -> Vec2

Returns the one vector (1, 1).

pub const fn unit_x() -> Vec2

Returns the unit X vector (1, 0).

pub const fn unit_y() -> Vec2

Returns the unit Y vector (0, 1).

pub fn dot(self, other: Vec2) -> f32

Computes the dot product of two vectors.

pub fn length_squared(self) -> f32

Returns the squared length of the vector.

This is more efficient than length() when you only need to compare lengths.

pub fn length(self) -> f32

Returns the length (magnitude) of the vector.

pub fn normalize(self) -> Vec2

Returns a normalized (unit length) version of this vector.

If the vector has zero length, returns the zero vector.

pub fn lerp(self, other: Vec2, t: f32) -> Vec2

Linearly interpolates between two vectors.

When t = 0.0, returns self. When t = 1.0, returns other.

pub fn perpendicular(self) -> Vec2

Returns the perpendicular vector (rotated 90 degrees counter-clockwise).

Trait Implementations

impl Add for Vec2

type Output = Vec2

The resulting type after applying the + operator.

fn add(self, other: Vec2) -> Vec2

Performs the + operation.

impl Clone for Vec2

fn clone(&self) -> Vec2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vec2

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

Formats the value using the given formatter.

impl Default for Vec2

fn default() -> Vec2

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Vec2

fn deserialize<__D>( __deserializer: __D, ) -> Result<Vec2, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Div<f32> for Vec2

type Output = Vec2

The resulting type after applying the / operator.

fn div(self, scalar: f32) -> Vec2

Performs the / operation.

impl From<FfiVec2> for Vec2

fn from(v: FfiVec2) -> Vec2

Converts to this type from the input type.

impl From<Vector2<f32>> for Vec2

impl Mul<f32> for Vec2

type Output = Vec2

The resulting type after applying the * operator.

impl PartialEq for Vec2

fn eq(&self, other: &Vec2) -> bool
