| 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 href="#lifetime">Lifetime</a></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> |

| 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 |
