<p>This trait allows hash table lookup to be customized. It has one blanket

implementation that uses the regular solution with <code>Borrow</code> and <code>Eq</code>, just
|
|

like <code>HashMap</code> does, so that you can pass <code>&str</code> to lookup into a map with

|
<code>String</code> keys and so on.</p>
