Function vec4::clamp

pub fn clamp<'out, T>(
    out: &'out mut [T; 4], 
    a: &[T; 4], 
    b: &[T; 4]
) -> &'out mut [T; 4] where
    T: Clone + PartialOrd, 

Example

let mut v = [0.5_f32; 4];
vec4::clamp(&mut v, &vec4::new_zero(), &vec4::new_one());
assert_eq!(v, [0.5_f32; 4]);

let mut v = [-0.5_f32; 4];
vec4::clamp(&mut v, &vec4::new_zero(), &vec4::new_one());
assert_eq!(v, vec4::new_zero());

let mut v = [1.5_f32; 4];
vec4::clamp(&mut v, &vec4::new_zero(), &vec4::new_one());
assert_eq!(v, vec4::new_one());
