pub fn linux_random_u32() -> u32 ⓘAvailable on crate features
unsafe_syscall and linux only.Expand description
Generates a random u32 value that may not be criptographically secure.
It makes use of the GRND_NONBLOCK and GRND_INSECURE flags. So when the randomness
source is not ready, instead of blocking it may return less secure data in linux >= 5.6
or retry it a certain number of times, or even return 0 in some cases.
