This provide a fork method to "clone" an Rng. This is handy to initialize an Rng that needs to be given to another thread for example.

CHANGELOG.mdentrySummary
This provide a fork method to "clone" an Rng.
Motivation
This is handy to initialize an Rng that needs to be given to another thread for example.
rand_chachaused to provide a clonableChacha20Rng(arguably incorrect).chacha20::Chacha20Rngis not clonable. But it's convenient to fork RNGs when initializing a thread or whatnot.Details
