Struct hashers::jenkins::OAATHasher

pub struct OAATHasher(_);

The one-at-a-time Hasher. Relatively simple, but superseded by later algorithms.

From http://www.burtleburtle.net/bob/hash/doobs.html:

This is similar to the rotating hash, but it actually mixes the internal state. It takes 9n+9 instructions and produces a full 4-byte result. Preliminary analysis suggests there are no funnels.

This hash was not in the original Dr. Dobb's article. I implemented it to fill a set of requirements posed by Colin Plumb. Colin ended up using an even simpler (and weaker) hash that was sufficient for his purpose.
