pub fn fill_via_u64_chunks(src: &[u64], dest: &mut [u8]) -> (usize, usize)Expand description
Implement fill_bytes by reading chunks from the output buffer of a block
based RNG.
The return values are (consumed_u64, filled_u8).
filled_u8 is the number of filled bytes in dest, which may be less than
the length of dest.
consumed_u64 is the number of words consumed from src, which is the same
as filled_u8 / 8 rounded up.
See fill_via_u32_chunks for an example.
