<h3 id="overview"><a class="doc-anchor" href="#overview">§</a>Overview</h3>
|
|
<p>The <a href="https://crates.io/crates/regex"><code>regex</code></a> crate implements regular expression matching on strings and byte
|
|
arrays. However, in order to match the output of implementations of <code>fmt::Debug</code>
|
|
and <code>fmt::Display</code>, or by any code which writes to an instance of <code>fmt::Write</code>
|
|
or <code>io::Write</code>, it is necessary to first allocate a buffer, write to that
|
|
buffer, and then match the buffer against a regex.</p>
|
|
<p>In cases where it is not necessary to extract substrings, but only to test whether
|
|
or not output matches a regex, it is not strictly necessary to allocate and
|
|
write this output to a buffer. This crate provides a simple interface on top of
|
|
the lower-level <a href="https://crates.io/crates/regex-automata"><code>regex-automata</code></a> library that implements <code>fmt::Write</code> and
|
|
<code>io::Write</code> for regex patterns. This may be used to test whether streaming
|
|
output matches a pattern without buffering that output.</p>
|
|
<p>Users who need to extract substrings based on a pattern or who already have
|
|
buffered data should probably use the <a href="https://crates.io/crates/regex"><code>regex</code></a> crate instead.</p>
|
|
<h3 id="syntax"><a class="doc-anchor" href="#syntax">§</a>Syntax</h3>
|
|
<p>This crate uses the same <a href="https://docs.rs/regex-automata/0.1.7/regex_automata/#syntax">regex syntax</a> of the <code>regex-automata</code> crate.</p>
