Struct SecureRandom 

pub struct SecureRandom;

Stateless wrapper around Apple’s default CSPRNG.

Implementations

impl SecureRandom

pub fn fill(buffer: &mut [u8]) -> Result<()>

Fill an existing buffer with cryptographically secure random bytes.

Errors

Returns an error if Security.framework rejects the random-byte request.

pub fn bytes(length: usize) -> Result<Vec<u8>>

Allocate a new Vec<u8> and fill it with cryptographically secure random bytes.

Errors

Returns an error if Security.framework rejects the random-byte request.
