< 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 > )
