No, no, no, it does not. What is wrong with you people. Stop this. 
What even is this. You had an explicitly *non-cryptographic RNG* but you’re upset it doesn’t display cryptographic properties!?
Rust cryptography task force: wake up and get on top of this before your beloved language gets ruined by idiots who don’t even know what they want.
Q: I need a parachute. I’m curious if my new proposed design, which involves three Toyota seat belts and eight boxes of Kleenex will allow me to safely float to the ground.
We don’t need to handle severe crosswinds. We just need to feel safe jumping out of airplanes.
I’ve been downvoted on HN for making this point. I beg you, turn your back to that place if you ever want to do good engineering work.
There are, in fact, definitions of “good” that apply to non-cryptographic PRNGs. But non-invertability isn’t one of them. That’s a security property.
I want to live in a world where “random number generator” and “pseudorandom number generator” refer to secure things.
And there is this other class of things like “statistical sequence generator” that others can play with and make fast.

Ok I wrote down all my thoughts and will shut up now.
