Allows for greater use of Rng as a trait object. This is especially the case when one wants to do T::rand(rng) and 'rng' is some &mut Rng.

Think I already addressed this in my PR #161 (PR still needs a lot of work in general though). |

Preface: This is a breaking change!!
Recently I tried using
Randon aRngtrait object but I was unable to sinceRand::randrequires that theRngbeSized.This is mostly a proof-of-concept that should be considered when going through with the next iteration of this project.
Limitations:
chooseare implemented generically onRng. These cannot be used within the context of a trait object.if rng.gen() { ... }whenRngis notSized#[derive(Rand)]implementationgenandgen_range
