|
||
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>Deserializer</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>i8, i16, i32, i64, i128</li>
|
||
<li>u8, u16, u32, u64, u128</li>
|
||
<li>f32, f64</li>
|
||
<li>char</li>
|
||
</ul>
|
||
</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>
|
||
<li><strong>byte array</strong> - [u8]
|
||
<ul>
|
||
<li>Similar to strings, during deserialization byte arrays can be
|
||
transient, owned, or borrowed.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>option</strong>
|
||
<ul>
|
||
<li>Either none or some value.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>unit</strong>
|
||
<ul>
|
||
<li>The type of <code>()</code> in Rust. It represents an anonymous value containing
|
||
no data.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>unit_struct</strong>
|
||
<ul>
|
||
<li>For example <code>struct Unit</code> or <code>PhantomData<T></code>. It represents a named
|
||
value containing no data.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>unit_variant</strong>
|
||
<ul>
|
||
<li>For example the <code>E::A</code> and <code>E::B</code> in <code>enum E { A, B }</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>newtype_struct</strong>
|
||
<ul>
|
||
<li>For example <code>struct Millimeters(u8)</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>newtype_variant</strong>
|
||
<ul>
|
||
<li>For example the <code>E::N</code> in <code>enum E { N(u8) }</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>seq</strong>
|
||
<ul>
|
||
<li>A variably sized heterogeneous sequence of values, for example <code>Vec<T></code>
|
||
or <code>HashSet<T></code>. When serializing, the length may or may not be known
|
||
before iterating through all the data. When deserializing, the length
|
||
is determined by looking at the serialized data.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>tuple</strong>
|
||
<ul>
|
||
<li>A statically sized heterogeneous sequence of values for which the
|
||
length will be known at deserialization time without looking at the
|
||
serialized data, for example <code>(u8,)</code> or <code>(String, u64, Vec<T>)</code> or
|
||
<code>[u64; 10]</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>tuple_struct</strong>
|
||
<ul>
|
||
<li>A named tuple, for example <code>struct Rgb(u8, u8, u8)</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>tuple_variant</strong>
|
||
<ul>
|
||
<li>For example the <code>E::T</code> in <code>enum E { T(u8, u8) }</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>map</strong>
|
||
<ul>
|
||
<li>A heterogeneous key-value pairing, for example <code>BTreeMap<K, V></code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>struct</strong>
|
||
<ul>
|
||
<li>A heterogeneous key-value pairing in which the keys are strings and
|
||
will be known at deserialization time without looking at the serialized
|
||
data, for example <code>struct S { r: u8, g: u8, b: u8 }</code>.</li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>struct_variant</strong>
|
||
<ul>
|
||
<li>For example the <code>E::S</code> in <code>enum E { S { r: u8, g: u8, b: u8 } }</code>.</li>
|
||
</ul>
|
||
</li>
|
||
</ul>
|
||
<p>The <code>Deserializer</code> trait supports two entry point styles which enables
|
||
different kinds of deserialization.</p>
|
||
<ol>
|
||
<li>
|
||
<p>The <code>deserialize_any</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
|
||
Postcard 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 Postcard and many
|
||
others.</p>
|
||
<h2 id="lifetime"><a class="doc-anchor" href="#lifetime">§</a>Lifetime</h2>
|
||
<p>The <code>'de</code> lifetime of this trait is the lifetime of data that may be
|
||
borrowed from the input when deserializing. See the page <a href="https://serde.rs/lifetimes.html">Understanding
|
||
deserializer lifetimes</a> for a more detailed explanation of these lifetimes.</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>
