<p>By convention a Serde data format crate provides the following in the root
module or re-exported from the root module:</p>
<ul>
<li>An Error type common to both serialization and deserialization.</li>
<li>A Result typedef which is equivalent to std::result::Result<T, Error>.</li>
<li>A Serializer type which implements serde::Serializer.</li>
<li>A Deserializer type which implements serde::Deserializer.</li>
<li>One or more to_abc functions depending on what types the format supports
serializing to. For example to_string which returns a String, to_bytes which
returns a Vec<u8>, or to_writer which writes into an <a href="https://doc.rust-lang.org/std/io/trait.Write.html" target="_blank"><code>io::Write</code></a>.</li>
<li>One or more from_xyz functions depending on what types the format supports
deserializing from. For example from_str which takes a &str, from_bytes
which takes a &[u8], or from_reader which takes an <a href="https://doc.rust-lang.org/std/io/trait.Read.html" target="_blank"><code>io::Read</code></a>.</li>
</ul>
<p>In addition, formats that provide serialization-specific or
deserialization-specific APIs beyond Serializer and Deserializer should expose
those under top-level <code>ser</code> and <code>de</code> modules. For example serde_json provides a
pluggable pretty-printer trait as <a href="https://docs.rs/serde_json/1/serde_json/ser/trait.Formatter.html" target="_blank"><code>serde_json::ser::Formatter</code></a>.</p>
<p>A basic data format begins like this. The three modules are discussed in more
detail on the following pages.</p>
