1. docHead :: Doc -> (Maybe Char, Doc)

   ghc	GHC.Utils.Ppr

   Get the first character of a document. We also return a new document, equivalent to the original one but faster to render. Use it to avoid work duplication.

2. sHeader :: Scheme -> PprColour

   ghc	GHC.Utils.Ppr.Colour

   No documentation available.

3. parseBoundedHeader :: (ToHttpApiData a, Bounded a, Enum a) => ByteString -> Either Text a

   http-api-data	Web.HttpApiData

   Parse values based on ToHttpApiData instance. Uses toHeader to get possible values.

4. parseHeader :: FromHttpApiData a => ByteString -> Either Text a

   http-api-data	Web.HttpApiData

   Parse HTTP header value.

5. parseHeaderMaybe :: FromHttpApiData a => ByteString -> Maybe a

   http-api-data	Web.HttpApiData

   Parse HTTP header value in a Maybe.

   >>> parseHeaderMaybe "hello" :: Maybe Text
   Just "hello"
   

6. parseHeaderWithPrefix :: FromHttpApiData a => ByteString -> ByteString -> Either Text a

   http-api-data	Web.HttpApiData

   Parse given bytestring then parse the rest of the input using parseHeader.

   data BasicAuthToken = BasicAuthToken Text deriving (Show)
   
   instance FromHttpApiData BasicAuthToken where
   parseHeader h     = BasicAuthToken <$> parseHeaderWithPrefix "Basic " h
   parseQueryParam p = BasicAuthToken <$> parseQueryParam p
   

   >>> parseHeader "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==" :: Either Text BasicAuthToken
   Right (BasicAuthToken "QWxhZGRpbjpvcGVuIHNlc2FtZQ==")
   

7. toHeader :: ToHttpApiData a => a -> ByteString

   http-api-data	Web.HttpApiData

   Convert to HTTP header value.

8. parseBoundedHeader :: (ToHttpApiData a, Bounded a, Enum a) => ByteString -> Either Text a

   http-api-data	Web.Internal.HttpApiData

   Parse values based on ToHttpApiData instance. Uses toHeader to get possible values.

9. parseHeader :: FromHttpApiData a => ByteString -> Either Text a

   http-api-data	Web.Internal.HttpApiData

   Parse HTTP header value.

10. parseHeaderMaybe :: FromHttpApiData a => ByteString -> Maybe a

    http-api-data	Web.Internal.HttpApiData

    Parse HTTP header value in a Maybe.

    >>> parseHeaderMaybe "hello" :: Maybe Text
    Just "hello"
