Better documentation

[andreclaudino]

I am a Rust user and I am becoming a qdrant fan. I want to use qdrant in a production project with Rust. Unfortunately I miss a beter documentation where not only examples but possibilities and how to use types are covered.

Wich are the available features of the crate, what does each function does, what each type does and how to create them from other common types like vectors and serde_json::Value, these are just some examples of questions that could be answered in a beter documentation.

I would like to help with that, but I will need the help of the developers to create that.

These docs are sad. One example, text matching foo, bar, baz? Who maintains this? Wake up. How do you vector search to disambiguate terminology with the qdrant vector database rust client?

Without docs, this code isn't too useful. Just feel concerned because I wanted to make a demo with your crate because it's one of the only options for RAG in Rust, but after reviewing the docs and examples I'm not really feeling comfortable with this level of craftsmanship and attention to detail.

@timvisee @generall @agourlay come on! It's a developer tool, docs are a major dealbreaker for this potentially valuable project, why waste time writing code if no one but you can figure out how to use it without reverse engineering your tests and stuff?

Hi @bionicles, your contributions are welcome

Hi @bionicles. Thank you for pointing this out once again.

You're right. It isn't in the best state. Because of that we're planning to rework and polish the Rust client to make it a lot easier to work with, while maintaining minimal to no breakage each update (https://github.com/qdrant/rust-client/issues/87). I cannot give an estimate on this though, as we're still starting these efforts.

In the mean time I would like to point out that we recently added Rust examples everywhere in our general documentation. So I recommend to use it as resource rather than the crate documentation. For example: https://qdrant.tech/documentation/concepts/points/

thank you @timvisee i'll check it out! @generall if i find anything simple and reproducible i'll be sure to include it; sadly this dataset I'm using has weird license terms so I might have difficulty sharing the test cases for the current project

Try this Makefile and #![warn(missing_docs)] or #![deny(missing_docs)]

make nextest and make test / test-docs / test-stable for fast nightly / fast docs / normal tests make watch ought to be decent for dev mode when cranking
