  110. <p>
  111. Prefix searches with a type followed by a colon (e.g.
  112. <code>fn:</code>) to restrict the search to a given type.
  113. </p>
  114. <p>
  115. Accepted types are: <code>fn</code>, <code>mod</code>,
  116. <code>struct</code>, <code>enum</code>,
  117. <code>trait</code>, <code>type</code>, <code>macro</code>,
  118. and <code>const</code>.
  119. </p>
  120. <p>
  121. Search functions by type signature (e.g.
  122. <code>vec -> usize</code> or <code>* -> vec</code>)
