If <code>std</code> is enabled these will be generated upon first invocation.
|
|
Otherwise if the <code>compile-time-rng</code>feature is enabled these will be generated at compile time.
|
|
If neither of these features are available, hardcoded constants will be used.</p>
|
|
<p>Because the values are fixed, different hashers will all hash elements the same way.
|
|
This could make hash values predictable, if DOS attacks are a concern. If this behaviour is

not required, it may be preferable to use <a href="random_state/struct.RandomState.html" title="struct ahash::random_state::RandomState">RandomState</a> instead.</p>
