source

pub fn new(value: Vec2) -> Result<Self, InvalidDirectionError>

Create a direction from a finite, nonzero Vec2, normalizing it.

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

source

pub fn new_unchecked(value: Vec2) -> Self

Create a Dir2 from a Vec2 that is already normalized.

§Warning

value must be normalized, i.e its length must be 1.0.

source

pub fn new_and_length(value: Vec2) -> Result<(Self, f32), InvalidDirectionError>

Create a direction from a finite, nonzero Vec2, normalizing it and also returning its original length.

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

source

pub fn from_xy(x: f32, y: f32) -> Result<Self, InvalidDirectionError>

Create a direction from its x and y components.

Returns Err(InvalidDirectionError) if the length of the vector formed by the components is zero (or very close to zero), infinite, or NaN.

source

pub const fn as_vec2(&self) -> Vec2

source

pub fn slerp(self, rhs: Self, s: f32) -> Self

Performs a spherical linear interpolation between self and rhs based on the value s.

This corresponds to interpolating between the two directions at a constant angular velocity.

When s == 0.0, the result will be equal to self. When s == 1.0, the result will be equal to rhs.

§Example
let dir1 = Dir2::X;
let dir2 = Dir2::Y;

let result1 = dir1.slerp(dir2, 1.0 / 3.0);
assert_relative_eq!(result1, Dir2::from_xy(0.75_f32.sqrt(), 0.5).unwrap());

let result2 = dir1.slerp(dir2, 0.5);
assert_relative_eq!(result2, Dir2::from_xy(0.5_f32.sqrt(), 0.5_f32.sqrt()).unwrap());
