Can tantivy::collector::facet_collector::FacetCounts be exported to pub?

[slckl]

Sorry, if I'm missing something obvious here, but...

As a user of Tantivy as a library and using a FacetCollector, I'd like to write a function that takes in FacetCounts and process the results into something more fit for my application. Alas, the FacetCounts struct is not exported as public for users of Tantivy.
I can only process the facet counts inside the same function I obtain the results in. This approach works, but limits how I as a user can organize my code around FacetCounts.

Are there any downsides to this type being exported publicly? Maybe in the same tantivy::collector module?

An alternative could be to use MultiCollector, which returns MultiFruit, from which you can extract results for each collector using a handle. Alas, MultiFruit is also not exported publicly, so there goes that plan.

Going with processing in-place for now, but I still think it would be nice, if I could write a separate function for each collector separately.

I am ok to make it pub. Can you for tantivy, make it pub on your fork, depend on your fork to check that it addresses your problem, and send a PR?

I'd hate to make it pub, and then realize it is not sufficient to fix your problem.
