Trait Rng 

pub trait Rng {
    // Required method
    fn fill_bytes(&self, dest: &mut [u8]);
}

Trait boundary for cryptographically-secure random byte production.

Implementations MUST produce cryptographically strong randomness. Failing to do so defeats replay protection (DPoP nonces) and capability-ID unpredictability. The trait deliberately exposes only fill_bytes so adapters can route to CSPRNG primitives native to their platform without extra shims.

Required Methods

fn fill_bytes(&self, dest: &mut [u8])

Fill dest with cryptographically secure random bytes.

Implementations on Foreign Types
