Function quat::lerp

pub fn lerp<T, F>(
    out: &'out mut [T; 4], 
    a: &[T; 4], 
    b: &[T; 4], 
    t: &F
) -> &'out mut [T; 4] where
    F: Clone + Cast<T> + MulAssign<&'a F>,
    T: Clone + Cast<F> + AddAssign<&'a T>,
    &'a T: Sub<&'b T>,
    <&'a T as Sub<&'b T>>::Output == T, 

Example

let mut v = vec4::new_zero();
vec4::lerp(&mut v, &vec4::new_zero(), &[100; 4], &0.5);
assert_eq!(v, [50; 4]);
