Debugging Rust with Visual Studio Code

• Install VS Code
• (Not recommended for non-Mac OSs) Follow this blog post to setup debugging with breakpoints using LLDB in VS Code.
• (Not recommended as using RLS and Native Debug with the below launch.json should be simpler). Troubleshoot by following these steps
• Example Debug Config file Diamond-drops/.vscode/launch.json. Use by going to menu: Debug > Start Debugging. Note that you shouldn't have to build the project first, as running these debuggers will just run cargo run -mode c for example.
• Further information is here. Use CTRL+P before entering ext install <insert-extension>.

See the .vscode in this folder for the latest changes available in the develop branch. /diamond_drops/.vscode/launch.json:
