Why Discord is switching from Go to Rust (2020)

Yes we are using rust in a big way. We have multiple teams now full time working on Rust. It is being used on both the client and server, as native modules, web assembly, and also native rust services and NIFs that embed themselves in our elixir services.

It has been an incredible success. I plan to blog more about it in the coming months. Our usage of Rust is continuing to grow, and if you check out our jobs page, you might notice all backend / infra jobs list Rust in them now :)

I think probably 40% of requests are handled directly by rust services now, with the rest involving one or more rust service called from our Python API layer.

Bit of a late reply, but how does Elixir fit into the overall strategy? Is it still like how it is described in previous engineering blogs where it acts as a kind of orchestrator for guilds?

I love Rust elixir Nifs. Gives you the best of both worlds to be honest. Highly fault tolerant code with fast computation. Only downside is that it can't really handle extreme crashes like a native process can.

Erlang/Elixir + Rust is an awesome couple. For the downside you mentioned, depending on the use case, it could be interesting to use Rust as a node: https://github.com/sile/erl_dist

Very nice. Nodes are great if you want a long running system along side your elixir app.
