pub fn read_data_header<'de, R: Reader<'de>>(
_r: &mut WxfReader<R>,
_n_data: usize,
) -> Result<(), Error>Expand description
No-op: the old strategy needed a separate "Data" key + List header;
the new format inlines data directly after the variant name, so there
is nothing extra to read. Kept for API compatibility with derived code.
