My Primary use case for irust is to test/play with crates I'm working on with :add --path. One annoying part of this is having to edit the source file and set an item's visibility to pub every time I want to access it. It would be great to have the option to add a crate with all items marked as pub automatically.
I think we can do this by copying the source code to a temporary directory and using syn and prettyplease on all .rs files to change the visibility of all items before the call to cargo add.
If this is something that the project is open to, I can make a PR.
