|
||
<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>

||
size without the need for version negotiation.</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.

<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>)
