<p>Serde is a framework for <strong><em>ser</em></strong>ializing and <strong><em>de</em></strong>serializing Rust data
structures efficiently and generically.</p>
<p>The Serde ecosystem consists of data structures that know how to serialize
and deserialize themselves along with data formats that know how to
serialize and deserialize other things. Serde provides the layer by which
these two groups interact with each other, allowing any supported data
structure to be serialized and deserialized using any supported data format.</p>
<p>See the Serde website <a href="https://serde.rs/">https://serde.rs/</a> for additional documentation and
usage examples.</p>
<h2 id="design" class="section-header"><a href="#design">Design</a></h2>
<p>Where many other languages rely on runtime reflection for serializing data,
Serde is instead built on Rust's powerful trait system. A data structure
that knows how to serialize and deserialize itself is one that implements
Serde's <code>Serialize</code> and <code>Deserialize</code> traits (or uses Serde's derive
attribute to automatically generate implementations at compile time). This
avoids any overhead of reflection or runtime type information. In fact in
many situations the interaction between data structure and data format can
be completely optimized away by the Rust compiler, leaving Serde
serialization to perform the same speed as a handwritten serializer for the
specific selection of data structure and data format.</p>
<h2 id="data-formats" class="section-header"><a href="#data-formats">Data formats</a></h2>
<p>The following is a partial list of data formats that have been implemented
for Serde by the community.</p>
<ul>
<li><a href="https://github.com/serde-rs/json">JSON</a>, the ubiquitous JavaScript Object Notation used by many HTTP APIs.</li>
<li><a href="https://github.com/TyOverby/bincode">Bincode</a>, a compact binary format
used for IPC within the Servo rendering engine.</li>
<li><a href="https://github.com/pyfisch/cbor">CBOR</a>, a Concise Binary Object Representation designed for small message
size without the need for version negotiation.</li>
<li><a href="https://github.com/dtolnay/serde-yaml">YAML</a>, a popular human-friendly configuration language that ain't markup
language.</li>
<li><a href="https://github.com/3Hren/msgpack-rust">MessagePack</a>, an efficient binary format that resembles a compact JSON.</li>
<li><a href="https://github.com/alexcrichton/toml-rs">TOML</a>, a minimal configuration format used by <a href="http://doc.crates.io/manifest.html">Cargo</a>.</li>
<li><a href="https://github.com/birkenfeld/serde-pickle">Pickle</a>, a format common in the Python world.</li>
<li><a href="https://github.com/laktak/hjson-rust">Hjson</a>, a variant of JSON designed to be readable and writable by humans.</li>
<li><a href="https://github.com/zonyitoo/bson-rs">BSON</a>, the data storage and network transfer format used by MongoDB.</li>
<li><a href="https://github.com/flavray/avro-rs">Avro</a>, a binary format used within Apache Hadoop, with support for schema
definition.</li>
<li><a href="https://github.com/nox/serde_urlencoded">URL</a>, the x-www-form-urlencoded format.</li>
<li><a href="https://github.com/RReverser/serde-xml-rs">XML</a>, the flexible machine-friendly W3C standard.
<em>(deserialization only)</em></li>
<li><a href="https://github.com/softprops/envy">Envy</a>, a way to deserialize environment variables into Rust structs.
<em>(deserialization only)</em></li>
<li><a href="https://github.com/OneSignal/serde-redis">Redis</a>, deserialize values from Redis when using <a href="https://crates.io/crates/redis">redis-rs</a>.

<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>)
