<p>Lots of things in Rust are punctuated sequences.</p>
<ul>
<li>The fields of a struct are <code>Punctuated<Field, Token![,]></code>.</li>
<li>The segments of a path are <code>Punctuated<PathSegment, Token![::]></code>.</li>
<li>The bounds on a generic parameter are <code>Punctuated<TypeParamBound, Token![+]></code>.</li>
<li>The arguments to a function call are <code>Punctuated<Expr, Token![,]></code>.</li>
</ul>
<p>This module provides a common representation for these punctuated sequences
in the form of the <ahref="struct.Punctuated.html"title="struct syn::punctuated::Punctuated"><code>Punctuated<T, P></code></a> type. We store a vector of pairs of
syntax tree node + punctuation, where every node in the sequence is followed
by punctuation except for possibly the final one.</p>
