int8 :: Parser Int8

Produces the next byte and advances the parser.

int16 :: Parser Int16

Produces a signed 16-bit integer and advances the parser.

int32 :: Parser Int32

Produces a signed 32-bit integer and advances the parser.

int64 :: Parser Int64

Produces a signed 64-bit integer and advances the parser.

double :: Parser Double

Produces a 64-bit floating point number and advances the parser.

take :: Int -> Parser ByteString

take n gets exactly n bytes or fails the parse.
