Documentation
tryInput :: FromBytes a => IO (Either String a) Source #
Get plugin input, returning an error message if the encoding is invalid
inputByteString :: IO ByteString Source #
Get plugin input as a ByteString
inputString :: IO String Source #
Get plugin input as a String
inputJSON :: Data a => IO a Source #
Get input as JSON, this is similar to calling `input (JsonValue ...)`
outputJSON :: Data a => a -> IO () Source #
Set plugin output to a JSON encoded version of the provided value
class ToBytes a where Source #
A class used to convert values to bytes to be written into linear memory
Methods
toBytes :: a -> ByteString Source #
Instances
class FromBytes a where Source #
