54 <p>PRNG implementations are allowed to assume that bits in the seed are
55 well distributed. That means usually that the number of one and zero
56 bits are roughly equal, and values like 0, 1 and (size - 1) are unlikely.
57 Note that many non-cryptographic PRNGs will show poor quality output
58 if this is not adhered to. If you wish to seed from simple numbers, use
59 <code>seed_from_u64</code> instead.</p>
60 <p>All PRNG implementations should be reproducible unless otherwise noted:
61 given a fixed <code>seed</code>, the same sequence of output should be produced
62 on all runs, library versions and architectures (e.g. check endianness).
63 Any “value-breaking” changes to the generator should require bumping at
64 least the minor version and documentation of the change.</p>
65 <p>It is not required that this function yield the same state as a
66 reference implementation of the PRNG given equivalent seed; if necessary
67 another constructor replicating behaviour from a reference
68 implementation can be added.</p>
69 <p>PRNG implementations should make sure <code>from_seed</code> never panics. In the
70 case that some special values (like an all zero seed) are not viable
71 seeds it is preferable to map these to alternative constant value(s),
72 for example <code>0xBAD5EEDu32</code> or <code>0x0DDB1A5E5BAD5EEDu64</code> (“odd biases? bad
