|
||
<p>Most of the regex engines in this crate require some kind of
|
||
mutable state in order to execute a search. This mutable state is
|
||
explicitly separated from the core regex object (such as a
|
||
<a href="../nfa/thompson/struct.NFA.html" title="struct regex_automata::nfa::thompson::NFA"><code>thompson::NFA</code></a>) so that the read-only regex
|
||
object can be shared across multiple threads simultaneously without any
|
||
synchronization. Conversely, a <code>Cache</code> must either be duplicated if using
|
||
the same <code>Regex</code> from multiple threads, or else there must be some kind of
|
||
synchronization that guarantees exclusive access while it’s in use by one
|
||
thread.</p>
|
||
<p>A <code>Regex</code> attempts to do this synchronization for you by using a thread
|
||
pool internally. Its size scales roughly with the number of simultaneous
|
||
regex searches.</p>
|
||
<p>For cases where one does not want to rely on a <code>Regex</code>’s internal thread
|
||
pool, lower level routines such as <a href="struct.Regex.html#method.search_with" title="method regex_automata::meta::Regex::search_with"><code>Regex::search_with</code></a> are provided
|
||
that permit callers to pass a <code>Cache</code> into the search routine explicitly.</p>
|
||
<p>General advice is that the thread pool is often more than good enough.
|
||
However, it may be possible to observe the effects of its latency,
|
||
especially when searching many small haystacks from many threads
|
||
simultaneously.</p>
|
||
<p>Caches can be created from their corresponding <code>Regex</code> via
|
||
<a href="struct.Regex.html#method.create_cache" title="method regex_automata::meta::Regex::create_cache"><code>Regex::create_cache</code></a>. A cache can only be used with either the <code>Regex</code>
|
||
that created it, or the <code>Regex</code> that was most recently used to reset it
|
||
with <a href="struct.Cache.html#method.reset" title="method regex_automata::meta::Cache::reset"><code>Cache::reset</code></a>. Using a cache with any other <code>Regex</code> may result in
|
||
panics or incorrect results.</p>
