<h2 id="syntax"><a class="doc-anchor" href="#syntax">§</a>Syntax</h2>
|
|
<p>Rust has six types of attributes.</p>
|
|
<ul>
|
|
<li>Outer attributes like <code>#[repr(transparent)]</code>. These appear outside or
|
|
in front of the item they describe.</li>
|
|
<li>Inner attributes like <code>#![feature(proc_macro)]</code>. These appear inside
|
|
of the item they describe, usually a module.</li>
|
|
<li>Outer doc comments like <code>/// # Example</code>.</li>
|
|
<li>Inner doc comments like <code>//! Please file an issue</code>.</li>
|
|
<li>Outer block comments <code>/** # Example */</code>.</li>
|
|
<li>Inner block comments <code>/*! Please file an issue */</code>.</li>
|
|
</ul>
|
|
<p>The <code>style</code> field of type <code>AttrStyle</code> distinguishes whether an attribute
|
|
is outer or inner. Doc comments and block comments are promoted to
|
|
attributes, as this is how they are processed by the compiler and by
|
|
<code>macro_rules!</code> macros.</p>
|
|
<p>The <code>path</code> field gives the possibly colon-delimited path against which
|
|
the attribute is resolved. It is equal to <code>"doc"</code> for desugared doc
|
|
comments. The <code>tokens</code> field contains the rest of the attribute body as
|
|
tokens.</p>
|
|

<h2 id="parsing-from-attribute-to-structured-arguments"><a class="doc-anchor" href="#parsing-from-attribute-to-structured-arguments">§</a>Parsing from Attribute to structured arguments</h2>
|
|
<p>The grammar of attributes in Rust is very flexible, which makes the
|
|
syntax tree not that useful on its own. In particular, arguments of the
|
|
attribute are held in an arbitrary <code>tokens: TokenStream</code>. Macros are
|
|
expected to check the <code>path</code> of the attribute, decide whether they
|
|
recognize it, and then parse the remaining tokens according to whatever
|
|
grammar they wish to require for that kind of attribute.</p>
|
|
<p>If the attribute you are parsing is expected to conform to the
|
|
conventional structured form of attribute, use <a href="struct.Attribute.html#method.parse_meta" title="method syn::Attribute::parse_meta"><code>parse_meta()</code></a> to
|
|
obtain that structured representation. If the attribute follows some
|
|
other grammar of its own, use <a href="struct.Attribute.html#method.parse_args" title="method syn::Attribute::parse_args"><code>parse_args()</code></a> to parse that into the
|
|
expected data structure.</p>
|
|
<p><br></p>
|
|
<h2 id="doc-comments"><a class="doc-anchor" href="#doc-comments">§</a>Doc comments</h2>
|
|
<p>The compiler transforms doc comments, such as <code>/// comment</code> and <code>/*! comment */</code>, into attributes before macros are expanded. Each comment is
|
|
expanded into an attribute of the form <code>#[doc = r"comment"]</code>.</p>
|
|
<p>As an example, the following <code>mod</code> items are expanded identically:</p>
|
|
|
|
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">let </span>doc: ItemMod = <span class="macro">parse_quote!</span> {

</span><span class="kw">mod </span>example {
