Different tantivy index writer per handler

[soasada]

Hi, I'm new to axum and rust, so bear with me.

I'm trying to create a small search engine with axum and tantivy. As tantivy docs said only one index writer is allowed, and is thread safe. I have different things to index (articles, questions and products), so I will have one index writer per entity and one handler for each entity to index.

How can I pass those index writers to different handlers? something like a map of index writers and use a state with the map? or shall I use another mechanism? I was thinking in function currying, a function that takes an index writer and returns you an axum handler, but it's not an easy task.

Any ideas?
