Sources for obtaining entropy.

Re-exports

pub use windows::entropy_from_system;

An entropy generator for Windows, using WinAPI's BCryptGenRandom function.

backup_entropy	A backup entropy source, trying rdseed first, and if it fails or does not complete, combining it with or using system time-based entropy generation.
emergency_system_time_entropy	An emergency system time-based entropy source. Should be slightly better than just piping the system time into a seed, but for the love of god, don't use this unless you have a REALLY good reason.
rdseed_entropy	An rdseed-based entropy source. Only works on x86/x86_64 platforms where the `rdseed` instructions are available. Returns `None` if `rdseed` is not available. Returns `Ok` if it sucesfully managed to pull the requested amount of bytes. Returns `Err` if it couldn't pull the requested amount of bytes. VERY unreliable.
