Hey guys,

I finished my first larger project in Rust today and would like to have some feedback on it! Depending on the point of view the capabilities are quite basic and the project currently resembles rather a dark pool than a transparent exchange. The client can't query the currently active limit order book yet and I have some "obvious violations" like storing passwords unhashed in there but that's all coming, don't worry. :)

Nice job! It's good to see Rust implementations in the financial domain. I believe it's an excellent language with a bright future for many use cases in finance (both operations and research) but I haven't really seen it used that much yet.

Thanks! Yes, it seems very well suited for it. The financial sector is slow in adapting new technology (with a few exceptions). We need to show what can be built and how stable the new software can be. Adaption will come :)

Very true. While I'm skeptical of things like the blockchain as "the main course" in financial innovation, I noticed there's some general strive towards getting things right and up to date on the tech side of the equation. IEX and Alpaca for example. Whatever it may be, I see Rust on the forefront as its principles make handling things like instrument pricing and managing orders a real pleasure.
