sinkGet :: MonadThrow m => Get r -> Consumer ByteString m r

Convert a Get into a Sink. The Get will be streamed bytes until it returns Done or Fail.

If Get succeed it will return the data read and unconsumed part of the input stream. If the Get fails due to deserialization error or early termination of the input stream it raise an error.

conduitGet :: MonadThrow m => Get o -> Conduit ByteString m o

Run a Get repeatedly on the input stream, producing an output stream of whatever the Get outputs.

sourcePut :: Monad m => Put -> Producer m ByteString

Convert a Put into a Source. Runs in constant memory.

conduitPut :: Monad m => Putter a -> Conduit a m ByteString

Run a Putter repeatedly on the input stream, producing a concatenated ByteString stream.
