The class

class (IsString p, Semigroup p, Monoid p) => Printer p where Source #

Text monoid. string must be equivalent to fromString and be a monoid homomorphism, i.e. string mempty = mempty and mappend (string x) (string y) = string (mappend x y). Other operations must be monoid homomorphisms that are eqiuvalent (but possibly faster) to the composition of string and the corresponding embedding, e.g. text = string . unpack.

Minimal complete definition

Nothing

Methods

char :: Char -> p Source #

Print a character. char c must be equivalent to string [c], but hopefully is faster.

char7 :: Char -> p Source #

Print an ASCII character, can be faster than char.

string :: String -> p Source #

Print a string.

string7 :: String -> p Source #

Print an ASCII string, can be faster than string.

text :: Text -> p Source #

Print a Text.

lazyText :: Text -> p Source #

Print a lazy Text.

ascii :: ByteString -> p Source #

Print an ASCII ByteString.

lazyAscii :: ByteString -> p Source #

Print a lazy ASCII ByteString.

utf8 :: ByteString -> p Source #

Print a UTF-8 ByteString.

lazyUtf8 :: ByteString -> p Source #

Print a lazy UTF-8 ByteString
