I use RustRover/VS Code + Codeium or Zed + Supermaven and I have used Copilot before. To be honest it takes some time to get used to the flow. I have turned them off multiple times and finally the workflow has set well in my brain. Now I feel very productive with them.

I work full-time for my own product (very early stage) but I am happy to share my own journey of using AI code assistants. Please feel free to check the commits: https://github.com/brainless/dwata
