| <p>For cross-platform reproducibility, these functions all use Little Endian: |
| least-significant part first. For example, <code>next_u64_via_u32</code> takes <code>u32</code> |
| values <code>x, y</code>, then outputs <code>(y << 32) | x</code>. To implement <code>next_u32</code> |
| from <code>next_u64</code> in little-endian order, one should use <code>next_u64() as u32</code>.</p> |
| <p>Byte-swapping (like the std <code>to_le</code> functions) is only needed to convert |
| to/from byte sequences, and since its purpose is reproducibility, |
| non-reproducible sources (e.g. <code>OsRng</code>) need not bother with it.</p> |
