Enum Linux Random Mode &nbsp; Copy item path

Secure

Cryptographic randomness, allowing the syscall to block.

This uses no getrandom flags.

SecureNonblock

Cryptographic randomness without blocking.

This uses GRND_NONBLOCK. If the kernel randomness source is not ready, the syscall may fail with EAGAIN.

Insecure

Non-cryptographic random bytes.

This uses GRND_INSECURE and is suitable only when cryptographic quality is not required.

Implementations§

impl LinuxRandomMode

Returns whether this mode is intended for cryptographic randomness.

pub const fn is_weak(self) -> bool
