rust-analyzer: rust-analyzer causes whole project to be invalidated… and rebuilt from scratch every code change :/

This is most serious bug I’ve encountered so far…

I use "rust-analyzer.checkOnSave.enable": false, setting… but rust-analyzer still does own checks, which causes cargo to rebuild the project from scratch every code change. It drives me crazy. Is there any workaround to tell rust-analyzer to just index, scan or whatever but no check/ clippy?
