We use the following tool to populate the outline view in vscode.

https://github.com/ramya-rao-a/go-outline

At present all it provides is package name and top-level functions. Compare this to the outline for say a node program where you get much more information (interfaces, enums, callbacks within funcs etc). At a minimum we should add the following info.

• package-level constants and vars
• interfaces
• structs/typedefs and their associated methods

Once this is working we can investigate if there's any info inside funcs/methods we want to include.
