FYI last week on my windows box : I miss clicked and launched a rust test in debug mode which launched the integrated debugger view in vscode but of course the test ran to completion without stopping since I didn't set a breakpoint, that triggered curiosity in human me, so I set a breakpoint in vscode, clicked "debug" and voilà, it actually worked and I didn't feel like I had to setup anything in particular. (I have VS2019 installed, and use the rust-analyzer vscode plugin)
