Function quat::div

pub fn div<'out, T>(
    out: &'out mut [T; 4], 
    a: &[T; 4], 
    b: &[T; 4]
) -> &'out mut [T; 4] where
    T: Add<T, Output = T> + Sub<T, Output = T>,
    &'a T: Mul<&'b T, Output = T> + Neg<Output = T>, 

Example

use std::f32::consts::FRAC_2_PI;
let mut a = quat::new_identity::<f32>();
let mut b = quat::new_identity::<f32>();

quat::set_axis_angle(&mut a, &[0_f32, 0_f32, 1_f32], &FRAC_2_PI);
quat::set_axis_angle(&mut b, &[0_f32, 0_f32, 1_f32], &FRAC_2_PI);

let mut q = quat::new_identity::<f32>();
quat::div(&mut q, &a, &b);
assert_eq!(q, [0_f32, 0_f32, 0_f32, 1_f32]);

let mut axis = [0_f32; 3];
let angle = quat::axis_angle(&mut q, &mut axis);

assert_eq!(angle, 0_f32);
assert_eq!(axis, [0_f32, 0_f32, 1_f32]);
