Module core::core_arch::x86::rdrand

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on x86 or x86-64 only.

RDRAND and RDSEED instructions for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source.

• _rdrand16_step^⚠rdrand
  Read a hardware generated 16-bit random value and store the result in val. Returns 1 if a random value was generated, and 0 otherwise.
• _rdrand32_step^⚠rdrand
  Read a hardware generated 32-bit random value and store the result in val. Returns 1 if a random value was generated, and 0 otherwise.
• _rdseed16_step^⚠rdseed
  Read a 16-bit NIST SP800-90B and SP800-90C compliant random value and store in val. Return 1 if a random value was generated, and 0 otherwise.
• _rdseed32_step^⚠rdseed
  Read a 32-bit NIST SP800-90B and SP800-90C compliant random value and store in val. Return 1 if a random value was generated, and 0 otherwise.
