<p>This function will check that the input is fully parsed. If there are
any unparsed tokens at the end of the stream, an error is returned.</p>
<p>This function parses a <code>proc_macro2::TokenStream</code> which is commonly useful
when the input comes from a node of the Syn syntax tree, for example the
body tokens of a <a href="struct.Macro.html" title="struct syn::Macro"><code>Macro</code></a> node. When in a procedural macro parsing the
<code>proc_macro::TokenStream</code> provided by the compiler, use <a href="fn.parse.html" title="fn syn::parse"><code>syn::parse</code></a>
instead.</p>
<p><em>This function is available only if Syn is built with the <code>"parsing"</code> feature.</em></p>
