Struct PackedFloatQuaternion 

#[repr(C, packed(1))]
pub struct PackedFloatQuaternion {
    pub x: f32,
    pub y: f32,
    pub z: f32,
    pub w: f32,
}

Packed quaternion for rotations.

C++ equivalent: MTL::PackedFloatQuaternion

Fields

x: f32

y: f32

z: f32

w: f32

Implementations

impl PackedFloatQuaternion

pub const fn new(x: f32, y: f32, z: f32, w: f32) -> Self

Create a new quaternion.

pub const fn identity() -> Self

Create an identity quaternion (no rotation).

pub const fn from_array(arr: [f32; 4]) -> Self

Create from an array.

pub const fn to_array(&self) -> [f32; 4]

Convert to an array.

impl PackedFloatQuaternion

pub fn get(&self, idx: usize) -> Option<f32>

Get element at index (0=x, 1=y, 2=z, 3=w).

Returns None if index is out of bounds.

Note: Cannot implement Index trait for packed structs due to alignment.

Trait Implementations

impl Clone for PackedFloatQuaternion

fn clone(&self) -> PackedFloatQuaternion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackedFloatQuaternion

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

Formats the value using the given formatter.

impl Default for PackedFloatQuaternion

fn default() -> PackedFloatQuaternion

Returns the “default value” for a type.

impl PartialEq for PackedFloatQuaternion

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