<div class='docblock'><p>Parses a JSON string as bytes. Note that this function does not check
whether the bytes represent a valid UTF-8 string.</p>
<p>The relevant part of the JSON specification is Section 8.2 of <a href="https://tools.ietf.org/html/rfc7159">RFC
7159</a>:</p>
<blockquote>
<p>When all the strings represented in a JSON text are composed entirely
of Unicode characters (however escaped), then that JSON text is
interoperable in the sense that all software implementations that
parse it will agree on the contents of names and of string values in
objects and arrays.</p>
<p>However, the ABNF in this specification allows member names and string
values to contain bit sequences that cannot encode Unicode characters;
for example, &quot;\uDEAD&quot; (a single unpaired UTF-16 surrogate). Instances
of this have been observed, for example, when a library truncates a
UTF-16 string without checking whether the truncation split a
surrogate pair. The behavior of software that receives JSON texts
containing such values is unpredictable; for example, implementations
might return different values for the length of a string value or even
suffer fatal runtime exceptions.</p>
</blockquote>
<p>The behavior of serde_json is specified to fail on non-UTF-8 strings
when deserializing into Rust UTF-8 string types such as String, and
succeed with non-UTF-8 bytes when deserializing using this method.</p>
<p>Escape sequences are processed as usual, and for <code>\uXXXX</code> escapes it is
still checked if the hex number represents a valid Unicode code point.</p>
<h1 id="examples" class="section-header"><a href="#examples">Examples</a></h1>
<p>You can use this to parse JSON strings containing invalid UTF-8 bytes.</p>

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
