Vim plugin for cargo.toml editing?

I generally use (neo)vim as IDE, because at to date it is pretty easy to use langserver servers and client plugins like LanguageClient-neovim to obtain something very powerful.

Thanks to RLS it is possible to use (neo)vim as a fantastic Rust IDE.

What I really miss is a feature I saw in VS code introduced by, I think, the RLS-vscode plugin: the interactive editing of the cargo.toml. In details, it shows interactively the versions available for a specific crate.

Is anyone aware of a (neo)vim plugin that introduces the same feature? It is not the end of the world if this is not available, but it will be surely handy.
