<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>
