Function radiant_rs::utils::approach

pub fn approach<T, S>(source_value: &mut T, target_value: &T, rate_of_change: S) where
    T: Add + Mul<S> + From<<<T as Mul<S>>::Output as Add>::Output> + Copy,
    S: Float,
    <T as Mul<S>>::Output: Add, 

Mutates source_value to approach target_value at the rate_of_change. Effectively a lerp that writes to source.
