Function quat::lmul_mut

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

lmul_mut(out, a) does out = out * a

Example

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