Struct Estimate 

pub struct Estimate { /* private fields */ }

How many times a loop probably runs.

For cost decisions and never for correctness. A pass asking whether unrolling pays for itself wants one of these, and it is fine for the answer to be a guess, because being wrong makes the code slower rather than wrong. Nothing here can be turned into a Bound.
