The programming language Nim also did a survey inspired by the Rust survey this year.
You can read their results and conclusions here. They mention and compare their results to what Rust users have answered in the Rust survey.
Interesting that Nim also attracts C and Python users like Rust did. Web development and server are also common topics of interest for both programming languages users.
I hope you’ll find it also interesting. It’s always good to have a look at what other programming languages are up to, especially if they talk about Rust.
