<p>The principal type in this module is a <ahref="struct.Pool.html"title="struct regex_automata::util::pool::Pool"><code>Pool</code></a>. It main use case is for
holding a thread safe collection of mutable scratch spaces (usually called
<code>Cache</code> in this crate) that regex engines need to execute a search. This then
permits sharing the same read-only regex object across multiple threads while
having a quick way of reusing scratch space in a thread safe way. This avoids
needing to re-create the scratch space for every search, which could wind up
being quite expensive.</p>
