renderQuery :: Bool -> Query -> Ascii
renderQueryBuilder :: Bool -> Query -> AsciiBuilder

-- | Convert <a>SimpleQuery</a> to <tt>ByteString</tt>.
renderSimpleQuery :: Bool -> SimpleQuery -> Ascii

-- | Split out the query string into a list of keys and values. A few
--   importants points:
--   
--   <ul>
--   <li>The result returned is still bytestrings, since we perform no
--   character decoding here. Most likely, you will want to use UTF-8
--   decoding, but this is left to the user of the library.</li>
--   <li>Percent decoding errors are ignored. In particular, <a>%Q</a> will
--   be output as <a>%Q</a>.</li>
--   </ul>
parseQuery :: ByteString -> Query

-- | Parse <a>SimpleQuery</a> from a <tt>ByteString</tt>.
parseSimpleQuery :: ByteString -> SimpleQuery

-- | Encodes a list of path segments into a valid URL fragment.
--   
--   This function takes the following three steps:
--   
--   <ul>
--   <li>UTF-8 encodes the characters.</li>
--   <li>Performs percent encoding on all unreserved characters, as well as
--   :@=+$,</li>
--   <li>Intercalates with a slash.</li>
--   </ul>
--   
--   For example:
--   
--   <pre>
--   encodePathInfo [\"foo\", \"bar\", \"baz\"]
--   </pre>
--   
--   "foo/bar/baz"
--   
--   <pre>
--   encodePathInfo [\"foo bar\", \"baz\/bin\"]
--   </pre>
--   
--   "foo%20bar/baz%2Fbin"
--   
--   <pre>
--   encodePathInfo [\"\"]
--   </pre>
--   
--   "%D7%A9%D7%9C%D7%95%D7%9D"
--   
--   Huge thanks to Jeremy Shaw who created the original implementation of
--   this function in web-routes and did such thorough research to
--   determine all correct escaping procedures.
