<div class='docblock'><p>Serializing Rust structures into TOML.</p>
|
|
|
|
|
|
|
|
|
|
|
|
<p>This module contains all the Serde support for serializing Rust structures
|
|
|
|
|
|
into TOML documents (as strings). Note that some top-level functions here
|
|
|
|
|
|
are also provided at the top of the crate.</p>
|
|
|
|
|
|
|
|
|
|
|
|
<p>Note that the TOML format has a restriction that if a table itself contains
|
|
|
|
|
|
tables, all keys with non-table values must be emitted first. This is
|
|
|
|
|
|
typically easy to ensure happens when you're defining a <code>struct</code> as you can
|
|
|
|
|
|
reorder the fields manually, but when working with maps (such as <code>BTreeMap</code>
|
|
|
|
|
|
or <code>HashMap</code>) this can lead to serialization errors. In those situations you
|
|
|
|
|
|
may use the <code>tables_last</code> function in this module like so:</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>)
|
|
|
|
|
|
