Given a ByteReadPacket, is there a way to peek instead of reading?
I don't want the read pointer to advance in certain circumstances

You use the Input.tryPeek and Input.peekTo methods.

Thanks @Aleksei Tirman [JB]. One thing I'm still failing to understand is how to get a ChunkBuffer.
It seems you have to "borrow" it? Also I can't specify a size it seems

Got it probably:

val buffer = ChunkBuffer(ByteBuffer.allocate(Int.SIZE_BYTES))
packet.peekTo(buffer)
