Methods
configEnumUtf8 :: e -> EnumUtf8Config Source #
Configures the textual representation of e generated by renderEnumUtf8.
renderEnumUtf8 :: e -> Utf8 Source #
Generate the standard textual representation according to
configEnumUtf8 by default.
parseEnumUtf8 :: Utf8 -> Possibly e Source #
Parses an e according to the renderEnumUtf8 render.
toFieldEnumUtf8 :: e -> ByteString Source #
A cassava field encoder, using 'the renderEnumUtf8' format.
fromFieldEnumUtf8_ :: Monad m => ByteString -> m e Source #
A cassava field parser using the renderEnumUtf8 format.
hashWithSaltEnumUtf8 :: Int -> e -> Int Source #
For hashing e with the renderEnumUtf8 representation.
class Utf8Parsable a where Source #
a class for Text parsers.
data EnumUtf8Config Source #
configures the default implementation of renderEnumUtf8
