Variants§

§

StreamHeader

The beginning of the stream.

The stream header contains the magic bytes (e.g. RRF2), the encoded version, and the encoding options.

After the stream header is read once, the state machine will only ever switch between MessageHeader and Message

§

MessageHeader

The beginning of a message.

The message header contains the number of bytes in the compressed message, and the number of bytes in the uncompressed message.

§

Message(MessageHeader)

The message content.

We need to know the full length of the message before attempting to read it, otherwise the call to decompress_into or the MessagePack deserialization may block or even fail.
