Serde.</p>
|
|||
|
|
<p>The role of this trait is to define the deserialization half of the <a href="https://serde.rs/data-model.html">Serde
|
|||
|
|
data model</a>, which is a way to categorize every Rust data type 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>Deserialize</code> map themselves into this data model by
|
|||
|
|
passing to the <code>Deserializer</code> a <code>Visitor</code> implementation that can receive
|
|||
|
|
these various types.</p>
|
|||
|
|
<p>The types that make up the Serde data model are:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><strong>14 primitive types</strong>
|

<ul>

<li>bool</li>

<li>u8, u16, u32, u64, u128</li>

<li><strong>string</strong>

|
<ul>
|
|||
|
|
<li>UTF-8 bytes with a length and no null terminator.</li>
|
|||
|
|
<li>When serializing, all strings are handled equally. When deserializing,

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

|
|
</ul>
|

|

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

transient, owned, or borrowed.</li>

|

data, for example <code>struct S { r: u8, g: u8, b: u8 }</code>.</li>

|
<p>The <code>Deserializer</code> trait supports two entry point styles which enables
|
|||
|
|
different kinds of deserialization.</p>
|
|||
|
|
<ol>
|
|||
|
|
<li>
|
|||
|
|
<p>The <code>deserialize</code> method. Self-describing data formats like JSON are able
|
|||
|
|
to look at the serialized data and tell what it represents. For example
|
|||
|
|
the JSON deserializer may see an opening curly brace (<code>{</code>) and know that
|
|||
|
|
it is seeing a map. If the data format supports
|
|||
|
|
<code>Deserializer::deserialize_any</code>, it will drive the Visitor using whatever
|
|||
|
|
type it sees in the input. JSON uses this approach when deserializing
|
|||
|
|
<code>serde_json::Value</code> which is an enum that can represent any JSON
|
|||
|
|
document. Without knowing what is in a JSON document, we can deserialize
|
|||
|
|
it to <code>serde_json::Value</code> by going through
|
|||
|
|
<code>Deserializer::deserialize_any</code>.</p>
|
|||
|
|
</li>
|
|||
|
|
<li>
|
|||
|
|
<p>The various <code>deserialize_*</code> methods. Non-self-describing formats like
|
|||
|
|
Bincode need to be told what is in the input in order to deserialize it.
|
|||
|
|
The <code>deserialize_*</code> methods are hints to the deserializer for how to
|
|||
|
|
interpret the next piece of input. Non-self-describing formats are not
|
|||
|
|
able to deserialize something like <code>serde_json::Value</code> which relies on
|
|||
|
|
<code>Deserializer::deserialize_any</code>.</p>
|
|||
|
|
</li>
|
|||
|
|
</ol>
|
|||
|
|
<p>When implementing <code>Deserialize</code>, you should avoid relying on
|
|||
|
|
<code>Deserializer::deserialize_any</code> unless you need to be told by the
|
|||
|
|
Deserializer what type is in the input. Know that relying on
|
|||
|
|
<code>Deserializer::deserialize_any</code> means your data type will be able to
|
|||
|
|
deserialize from self-describing formats only, ruling out Bincode and many
|
|||
|
|
others.</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>)
|
|||
|
|
