pub fn parse_section(text: &str, section: &str) -> BTreeMap<String, Vec<String>>Expand description
Any one section of a mimeapps.list — or of mimeinfo.cache,
which has the same shape and is read by this too (see
crate::apps::parse_cache).
The three that matter here are the defaults, the associations a
person added, and the ones they removed — see ADDED_SECTION and
REMOVED_SECTION. A removal is not a smaller kind of default: it
says “never offer this for that type”, and a chooser that ignores it
keeps putting back something somebody deliberately took away.
A key that appears twice in one section keeps the entries of both,
first occurrence first — the same “the earlier rule wins” the glob
matcher settled on, so that a caller taking .first() gets the
answer it would get from two files in directory order.
