An animation that returns time as its value.

Examples

let anim = pareen::id::<isize, isize>();

assert_eq!(anim.eval(-100), -100);
assert_eq!(anim.eval(0), 0);
assert_eq!(anim.eval(100), 100);
let anim = pareen::id::<f32, f32>() * 3.0 + 4.0;

assert_approx_eq!(anim.eval(0.0), 4.0);
assert_approx_eq!(anim.eval(100.0), 304.0);
