+/// A stream of bytes that iterates over borrowed data. It can produce single
+/// bytes or slices of memory and carries metadata about the read operation (for
+/// example a version).
+///
+/// The stream is intended for reading data without lookahead.
+///
+/// The state of the stream can be saved at any time with
+/// [`create_save_point`](ByteStream::create_save_point), and restored with
+/// [`restore_save_point`](ByteStream::restore_save_point).
+///
+/// NOTE: The save point *does not* restore the previous state of the metadata.
+/// It should therefore be avoided to modify the metadata while reading of
+/// composite structures data that might fail, for example multi-field structs
+/// that implement [`FromBytes`](crate::from_bytes::FromBytes).
