Struct rand::OsRng [] [src]

pub struct OsRng(_);

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

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]
