1. mapAcceptBytes :: [(ByteString, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapAccept that only takes ByteString as its input, to avoid ambiguous-type errors when using string literal overloading.

   getHeader >>= maybe render406Error encodeResourceWith . mapAcceptBytes
   [ ("abc", abc)
   , ("xyz", xyz)
   ]
   

2. mapAcceptCharset :: [(Charset, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapAccept that only takes Charset as its input, to avoid ambiguous-type errors when using string literal overloading.

   getHeader >>= maybe render406Error renderResource . mapAcceptCharset
   [ ("utf-8",    inUtf8)
   , ("us-ascii", inAscii)
   ]
   

3. mapAcceptEncoding :: [(Encoding, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapAccept that only takes Encoding as its input, to avoid ambiguous-type errors when using string literal overloading.

   getHeader >>= maybe render406Error renderResource . mapAcceptEncoding
   [ ("compress", compress)
   , ("identity", id)
   ]
   

4. mapAcceptLanguage :: [(Language, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapAccept that only takes Language as its input, to avoid ambiguous-type errors when using string literal overloading.

   getHeader >>= maybe render406Error renderResource . mapAcceptLanguage
   [ ("en-gb", inBritishEnglish)
   , ("fr",    inFrench)
   ]
   

5. mapAcceptMedia :: [(MediaType, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapAccept that only takes MediaType as its input, to avoid ambiguous-type errors when using string literal overloading.

   getHeader >>= maybe render406Error renderResource . mapAcceptMedia
   [ ("text/html",        asHtml)
   , ("application/json", asJson)
   ]
   

6. mapContent :: Accept a => [(a, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   The equivalent of matchContent above, except the resulting choice is mapped to another value.

   getContentType >>= maybe send415Error readRequestBodyWith . mapContent
   [ ("application" // "json", parseJson)
   , ("text" // "plain",       parseText)
   ]
   

7. mapContentCharset :: [(Charset, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapContent that only takes Charset as its input, to avoid ambiguous-type errors when using string literal overloading.

   getContentCharset >>=
   maybe send415Error readRequestBodyWith . mapContentCharset
   [ ("utf-8",    parseUtf8)
   , ("us-ascii", parseAscii)
   ]
   

8. mapContentEncoding :: [(Encoding, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapContent that only takes Encoding as its input, to avoid ambiguous-type errors when using string literal overloading.

   getContentEncoding >>=
   maybe send415Error readRequestBodyWith . mapContentEncoding
   [ ("compress", decompress)
   , ("identity", id)
   ]
   

9. mapContentLanguage :: [(Language, b)] -> ByteString -> Maybe b

   http-media	Network.HTTP.Media

   A specialisation of mapContent that only takes Language as its input, to avoid ambiguous-type errors when using string literal overloading.

   getContentLanguage >>=
   maybe send415Error readRequestBodyWith . mapContentLanguage
   [ ("en-gb", parseBritishEnglish)
   , ("fr",    parseFrench)
   ]
   

10. mapContentMedia :: [(MediaType, b)] -> ByteString -> Maybe b

    http-media	Network.HTTP.Media

    A specialisation of mapContent that only takes MediaType as its input, to avoid ambiguous-type errors when using string literal overloading.

    getContentType >>=
    maybe send415Error readRequestBodyWith . mapContentMedia
    [ ("application/json", parseJson)
    , ("text/plain",       parseText)
    ]
