pub fn diff_relations(
old_bytes: &[u8],
old_label: &str,
new_bytes: &[u8],
new_label: &str,
) -> Result<String, Refusal>Expand description
The difference between two workbooks (PORT.8, slice 8c): both files’
bytes read through the reader and compared, the changed relation and
the sheets in one file alone, one row a line in the fixed order
(reflect::diff::diff_text); each label is what a refusal calls its
file. Empty when the two hold the same sheets, names, Tables and cells.
