Expand description

Fill the given limbs slice with random bits.

NOTE: Assumes that the limbs in the given slice are zeroed!

When combined with a platform-independent “4-byte sequential” rng, this function is platform-independent. We consider an RNG “X-byte sequential” whenever rng.fill_bytes(&mut bytes[..i]); rng.fill_bytes(&mut bytes[i..]) constructs the same bytes, as long as i is a multiple of X. Note that the TryRng trait does not require this behaviour from rng.
