<p>The two most important traits in this module are <a href="../trait.Deserialize.html"><code>Deserialize</code></a> and
|
||||
<a href="../trait.Deserializer.html"><code>Deserializer</code></a>.</p>
|
||||
<ul>
|
||||
<li><strong>A type that implements <code>Deserialize</code> is a data structure</strong> that can be
|
||||
deserialized from any data format supported by Serde, and conversely</li>
|
||||
<li><strong>A type that implements <code>Deserializer</code> is a data format</strong> that can
|
||||
deserialize any data structure supported by Serde.</li>
|
||||
</ul>
|
||||
<h2 id="the-deserialize-trait"><a href="#the-deserialize-trait">The Deserialize trait</a></h2>
|
||||
<p>Serde provides <a href="../trait.Deserialize.html"><code>Deserialize</code></a> implementations for many Rust primitive and
|
||||
standard library types. The complete list is below. All of these can be
|
||||
deserialized using Serde out of the box.</p>
|
||||
<p>Additionally, Serde provides a procedural macro called <a href="https://crates.io/crates/serde_derive"><code>serde_derive</code></a> to
|
||||
automatically generate <a href="../trait.Deserialize.html"><code>Deserialize</code></a> implementations for structs and enums
|
||||
in your program. See the <a href="https://serde.rs/derive.html">derive section of the manual</a> for how to use this.</p>
|
||||
<p>In rare cases it may be necessary to implement <a href="../trait.Deserialize.html"><code>Deserialize</code></a> manually for
|
||||
some type in your program. See the <a href="https://serde.rs/impl-deserialize.html">Implementing <code>Deserialize</code></a> section of
|
||||
the manual for more about this.</p>
|
||||
<p>Third-party crates may provide <a href="../trait.Deserialize.html"><code>Deserialize</code></a> implementations for types
|
||||
that they expose. For example the <a href="https://crates.io/crates/linked-hash-map"><code>linked-hash-map</code></a> crate provides a
|
||||
<a href="https://docs.rs/linked-hash-map/*/linked_hash_map/struct.LinkedHashMap.html"><code>LinkedHashMap<K, V></code></a> type that is deserializable by Serde because the
|
||||
crate provides an implementation of <a href="../trait.Deserialize.html"><code>Deserialize</code></a> for it.</p>
|
||||
<h2 id="the-deserializer-trait"><a href="#the-deserializer-trait">The Deserializer trait</a></h2>
|
||||
<p><a href="../trait.Deserializer.html"><code>Deserializer</code></a> implementations are provided by third-party crates, for
|
||||
example <a href="https://github.com/serde-rs/json"><code>serde_json</code></a>, <a href="https://github.com/dtolnay/serde-yaml"><code>serde_yaml</code></a> and <a href="https://github.com/jamesmunns/postcard"><code>postcard</code></a>.</p>
|
||||
<p>A partial list of well-maintained formats is given on the <a href="https://serde.rs/#data-formats">Serde
|
||||
website</a>.</p>

||||
<h2 id="implementations-of-deserialize-provided-by-serde"><a href="#implementations-of-deserialize-provided-by-serde">Implementations of Deserialize provided by Serde</a></h2>
|
||||
<p>This is a slightly different set of types than what is supported for
|
||||
serialization. Some types can be serialized by Serde but not deserialized.
|
||||
One example is <code>OsStr</code>.</p>

|
||||
ever find yourself looking for a way to pass data into a <code>Deserialize</code> impl,
|
||||
this trait is the way to do it.</p>
|
||||
<p>As one example of stateful deserialization consider deserializing a JSON
|
||||
array into an existing buffer. Using the <code>Deserialize</code> trait we could
|
||||
deserialize a JSON array into a <code>Vec<T></code> but it would be a freshly allocated
|
||||
<code>Vec<T></code>; there is no way for <code>Deserialize</code> to reuse a previously allocated
|
||||
buffer. Using <code>DeserializeSeed</code> instead makes this possible as in the
|
||||
example code below.</p>
|
||||
<p>The canonical API for stateless deserialization looks like this:</p>
|
||||
|
||||
<div class='information'><div class='tooltip edition' data-edition="2018">ⓘ</div></div><div class="example-wrap"><pre class="rust rust-example-rendered edition"><code><span class="kw">fn</span> <span class="ident">func</span><span class="op"><</span><span class="lifetime">'de</span>, <span class="ident">T</span>: <span class="ident">Deserialize</span><span class="op"><</span><span class="lifetime">'de</span><span class="op">></span><span class="op">></span>() -> <span class="prelude-ty">Result</span><span class="op"><</span><span class="ident">T</span>, <span class="ident">Error</span><span class="op">></span></code></pre></div>
|
||||
<p>Adjusting an API like this to support stateful deserialization is a matter
|
||||
of accepting a seed as input:</p>
|
||||
|
||||
<div class='information'><div class='tooltip edition' data-edition="2018">ⓘ</div></div><div class="example-wrap"><pre class="rust rust-example-rendered edition"><code><span class="kw">fn</span> <span class="ident">func_seed</span><span class="op"><</span><span class="lifetime">'de</span>, <span class="ident">T</span>: <span class="ident">DeserializeSeed</span><span class="op"><</span><span class="lifetime">'de</span><span class="op">></span><span class="op">></span>(<span class="ident">seed</span>: <span class="ident">T</span>) -> <span class="prelude-ty">Result</span><span class="op"><</span><span class="ident">T::Value</span>, <span class="ident">Error</span><span class="op">></span></code></pre></div>
|
||||
<p>In practice the majority of deserialization is stateless. An API expecting a
|
||||
seed can be appeased by passing <code>std::marker::PhantomData</code> as a seed in the
|
||||
case of stateless deserialization.</p>
|
||||
<h2 id="lifetime"><a href="#lifetime">Lifetime</a></h2>
|
||||
<p>The <code>'de</code> lifetime of this trait is the lifetime of data that may be
|
||||
borrowed by <code>Self::Value</code> when deserialized. See the page <a href="https://serde.rs/lifetimes.html">Understanding
|
||||
deserializer lifetimes</a> for a more detailed explanation of these lifetimes.</p>
|
||||
<h2 id="example"><a href="#example">Example</a></h2>
|
||||
<p>Suppose we have JSON that looks like <code>[[1, 2], [3, 4, 5], [6]]</code> and we need
|
||||
to deserialize it into a flat representation like <code>vec![1, 2, 3, 4, 5, 6]</code>.
|
||||
Allocating a brand new <code>Vec<T></code> for each subarray would be slow. Instead we
|
||||
would like to allocate a single <code>Vec<T></code> and then deserialize each subarray
|
||||
into it. This requires stateful deserialization using the <code>DeserializeSeed</code>
|
||||
trait.</p>
