|
||
|
||
<p>The role of this trait is to define the serialization half of the Serde data
|
||
model, which is a way to categorize every Rust data structure into one of 27
|
||
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>
|
||
|
||
<ul>
|
||
<li><strong>12 primitive types</strong>
|
||
|
||
<ul>
|
||
<li>bool</li>
|
||
<li>i8, i16, i32, i64</li>
|
||
<li>u8, u16, u32, u64</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>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>

<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>)
