inline fun <R> BytePacketBuilder.preview(
    block: (tmp: ByteReadPacket) -> R
): R

Creates a temporary packet view of the packet being build without discarding any bytes from the builder. This is similar to build().copy() except that the builder keeps already written bytes untouched. A temporary view packet is passed as argument to block function and it shouldn’t leak outside of this block otherwise an unexpected behaviour may occur.
