I wrote it because i couldn't implement Consistent Hashing With Bounded Loads over any pre-existing golang consistent hashing packages in a clean way.
Here's the ugly code that made me into doing it: https://github.com/lafikl/liblb/blob/c9c4544834ac7ae7fa6a9cd...
I see now though...it's an approach to use a hash to decide which destination host to select...from a group of hosts used for load balancing.
