Thanks for taking interest in our project, we'd love to work with you.
We've compiled, for your convenience, a list of the most relevant questions and answers that you should know about before you contribute to the project.
It depends.
Our highest priority is to maintain great performance throughout feature releases. If your PR includes a kind of feature which inherently hinders performance considerably, it will unfortunately be rejected.
Other than that, all contributions are welcome.
cargo fmt and cargo clippy are your friends.
