tickets marketplace and digital goods e-commerce. Reliability and scalability is a key for us, we have lots of business logic and rust is super handy during refactorings. Actix has mature eco-system, hence our choice, also we leverage actors model quite intensively for scalability and logic decoupling.

I would love to learn more about what crates you use and how you manage infra. Do you blog about it by any chance?

Sure, sorry for late response, but ticketing one is opensource: https://github.com/bigneon/bn-api . Digital Assets is closed source but it's heavily using actors in addition to that and also using tokio-postgres instead of diesel.

We're running v2 in production too; I work for a financial exchange so low latency is key.

Totally makes sense. No reason Rust shouldn't take over the financial space. I know F# and other functional langs made some in-roads, but haven't heard anything about how far Rust has gotten yet.
