A source of randomness.

Required Methods§

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

🔬This is a nightly-only experimental API. (random #130703)

Fills bytes with random bytes.

Note that calling fill_bytes multiple times is not equivalent to calling fill_bytes once with a larger buffer. A RandomSource is allowed to return different bytes for those two cases. For instance, this allows a RandomSource to generate a word at a time and throw part of it away if not needed.
