Exilir and Rust would indeed be great additions to our integrations. However, we are really cautious when considering to support new languages. As said in the interview, we try to provide those API clients in the most idiomatic way for each language.

At the moment, we do not have a lot of demands for those languages nor the necessary workforce to onboard on those two languages (only very few people are proficient with those languages at Algolia and we don't have any production code using them IIRC).
