Struct zaplib::Quat

pub struct Quat {
    pub a: f32,
    pub b: f32,
    pub c: f32,
    pub d: f32,
}

Quaternion; used for rotations.

Let’s give it up for Hamilton.

Fields

a: f32

b: f32

c: f32

d: f32

Implementations

Trait Implementations

impl Clone for Quat

pub fn clone(&self) -> Quat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Quat

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

Formats the value using the given formatter.

impl Default for Quat

pub fn default() -> Quat

Returns the “default value” for a type.
