A random number generator that retrieves randomness straight from the
operating system.

This crate depends on [rand_core](https://crates.io/crates/rand_core) and is
part of the [Rand project](https://github.com/rust-random/rand).

This crate aims to support all of Rust's `std` platforms with a system-provided
entropy source. Unlike other Rand crates, this crate does not support `no_std`
(handling this gracefully is a current discussion topic).
