>>Reader objects are reusable Is there some special API need to invoke or just use the Reader object as directly?
I noticed that when a reader object has been used once, the subsequent read will failed. Is there some rewind operation need to be done just as the fread similar operation(i guess there may be some pointer internal)? my code example: kj::ArrayPtr<const kj::byte> byteArray((const kj::byte *) buf, (size_t) bufSize); kj::ArrayInputStream arrayInputStream(byteArray); kj::BufferedInputStreamWrapper input(arrayInputStream); capnp::PackedMessageReader message(input); maybe i need to rewind the inputstream to the begin so as to reuse the Reader object to retrive the target object?
