Show HN: Fast vector similarity using Rust and Python
I realize you have a different usecase in mind, so the following feedback might not be that useful to you.  I also haven’t reviewed your API design, so perhaps you have already considered this angle.<p>I picked up a habit in Go package design which I now apply everywhere: one of my immediate first thoughts when evaluating a library is how it creates or uses threads.<p>When I see that a library wants to consume all of the available cores of my system, or uses an internal task scheduler or threading mechanism, I worry that it will compete for CPU time with the other processes, threads, etc. that my system and process are using.<p>On the other hand, I appreciate when a library exposes an interface for me to offer it threads or a scheduler, or even better if it offers primitives that I can use directly in my own threads or tasks.<p>Perhaps this is mainly a problem for high-concurrency servers and UIs, but it’s always one of my first thoughts, and Rust is an ecosystem which needs to support those usecases.  Many threaded libraries, even otherwise very good ones, are not designed with this in mind and it is a problem.
