Function vec3::clamp

pub fn clamp<'out, T>(
    out: &'out mut [T; 3], 
    a: &[T; 3], 
    b: &[T; 3]
) -> &'out mut [T; 3] where
    T: Clone + PartialOrd, 

Example

let mut v = [0.5_f32; 3];
vec3::clamp(&mut v, &vec3::new_zero(), &vec3::new_one());
assert_eq!(v, [0.5_f32; 3]);

let mut v = [-0.5_f32; 3];
vec3::clamp(&mut v, &vec3::new_zero(), &vec3::new_one());
assert_eq!(v, vec3::new_zero());

let mut v = [1.5_f32; 3];
vec3::clamp(&mut v, &vec3::new_zero(), &vec3::new_one());
assert_eq!(v, vec3::new_one());
