When writing long-lived programs (daemons etc) in Rust, I find myself asking *where* I should put data.
In a GC'd language it's just "I have a string" but Rust forces me to find somewhere to put it.
You do get a performance benefit for this work though.
`init` feels like an unhelpful name in OO. It doesn't give you an initial value, it initialises the instance that has already been created. Developers are often surprised that init doesn't return the instance, because they have a strong association with `new Foo()`.
Perhaps `finish` would have been a less confusing name?

I do wonder whether hash DoS resistance is a good default. Sure, Rust programs are often pretty fast anyway, but it feels like a different threat model to the rest of Rust.
