//! This crate defines entropy generators. Here by "entropy"
//! we mean "true" (or close enough) randomness. We can think
//! of it as (potentially) slow random number generators, but
//! with high quality randomness.
//!
//! The crate is `#![no_std]`. But it does use external
//! os specific dependencies (e.g. `libc` or `windows-sys`).
