-/// A random number generator that retrieves randomness straight from
-/// the operating system. Platform sources:
-///
-/// - Unix-like systems (Linux, Android, Mac OSX): read directly from
-///   `/dev/urandom`, or from `getrandom(2)` system call if available.
-/// - OpenBSD: calls `getentropy(2)`
-/// - FreeBSD: uses the `kern.arandom` `sysctl(2)` mib
-/// - Windows: calls `RtlGenRandom`, exported from `advapi32.dll` as
-///   `SystemFunction036`.
-/// - iOS: calls SecRandomCopyBytes as /dev/(u)random is sandboxed.
-/// - PNaCl: calls into the `nacl-irt-random-0.1` IRT interface.
-///
-/// This usually does not block. On some systems (e.g. FreeBSD, OpenBSD,
-/// Max OS X, and modern Linux) this may block very early in the init
-/// process, if the CSPRNG has not been seeded yet.[1]
-///
-/// [1] See <https://www.python.org/dev/peps/pep-0524/> for a more
-///     in-depth discussion.
