Does this change serde's behavior? I need the field to match what I am getting in the JSON format

It will change the field name - so if you need it to match the JSON name then you can prefix it with:
#[allow(dead_code)]
sizes: Option<FxHashMap<String, Vec<SymInt>>>,
so it doesn't complain about the unread field.

ok, i'll need to do this. fortunately these are all defaulted so it doesn't matter too much yet

Just be aware that it only works with identifiers - so you can't do:
format!("{foo.bar}")
but you can do:
format!("{myvar}", myvar = foo.bar)

These are my suggestions - they're all pretty minor however. The biggest one is just the use of Result +
?in main - getting used to the rust style of error handling is pretty key since it's pretty pervasive.
