Function transform_mat3_mut 

pub fn transform_mat3_mut<'out, T>(
    out: &'out mut [T; 3],
    m: &[T; 9],
) -> &'out mut [T; 3]
where
    T: Clone + Add<T, Output = T>,
    for<'a, 'b> &'a T: Mul<&'b T, Output = T>,

Example

let mut v = vec3::new_one();
vec3::transform_mat3_mut(&mut v,
    &[1_f32, 0_f32, 0_f32, 0_f32, 1_f32, 0_f32, 0_f32, 0_f32, 1_f32],
);
assert_eq!(v, vec3::new_one());
