SeedRand

enum class SeedRand

strong

Enumerator
ZEROS	Seed with a compile time constant of zeros.
FIXED_SEED	Seed with a fixed value that never changes over the lifetime of this process. The seed is read from the RANDOM_CTX_SEED environment variable if set, otherwise generated randomly once, saved, and reused.
