hGetValue :: FromStruct ConstMsg a => Handle -> Int -> IO a

hGetValue limit handle reads a message from handle, returning its root object. limit is used as both a cap on the size of a message which may be read and, for types in the high-level API, the traversal limit when decoding the message.

getValue :: FromStruct ConstMsg a => Int -> IO a

getValue is equivalent to hGetValue stdin.

hPutValue :: (Cerialize RealWorld a, ToStruct (MutMsg RealWorld) (Cerial (MutMsg RealWorld) a)) => Handle -> a -> IO ()

hPutValue handle value writes value to handle, as the root object of a message.

putValue :: (Cerialize RealWorld a, ToStruct (MutMsg RealWorld) (Cerial (MutMsg RealWorld) a)) => a -> IO ()

putValue is equivalent to hPutValue stdin
