|
|
<p>The role of this trait is to define the serialization half of the <a href="https://serde.rs/data-model.html">Serde
|
|||
|
|
data model</a>, which is a way to categorize every Rust data structure into one
|
|||
|
|
of 29 possible types. Each method of the <code>Serializer</code> trait corresponds to
|
|||
|
|
one of the types of the data model.</p>
|
|||
|
|
<p>Implementations of <code>Serialize</code> map themselves into this data model by
|
|||
|
|
invoking exactly one of the <code>Serializer</code> methods.</p>
|
|||
|
|
<p>The types that make up the Serde data model are:</p>

<li>UTF-8 bytes with a length and no null terminator.</li>

there are three flavors of strings: transient, owned, and borrowed.</li>

<li><strong>byte array</strong> - [u8]

<p>Many Serde serializers produce text or binary data as output, for example
|
|||
|
|
JSON or Bincode. This is not a requirement of the <code>Serializer</code> trait, and
|
|||
|
|
there are serializers that do not produce text or binary output. One example
|
|||
|
|
is the <code>serde_json::value::Serializer</code> (distinct from the main <code>serde_json</code>
|
|||
|
|
serializer) that produces a <code>serde_json::Value</code> data structure in memory as
|
|||
|
|
output.</p>

<p>The default implementation of this method returns <code>true</code>. Data formats
|

|
|
may override this to <code>false</code> to request a compact form for types that
|
|||
|
|
support one. Note that modifying this method to change a format from
|
|||
|
|
human-readable to compact or vice versa should be regarded as a breaking
|
|||
|
|
change, as a value serialized in human-readable mode is not required to
|
|||
|
|
deserialize from the same data in compact mode.</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>)
|
|||
|
