Feature request: auto-complete version number in Cargo.toml

[azerupi]

I just got this idea when starting a new project recently and wanted to share it to see if it was possible.

When creating a new project, I always find myself adding a couple of dependencies. The procedure is always:

1. Type the name of the dependency in Cargo.toml
2. Find the latest version by going to crates.io or using cargo search <dep>
3. Fill in the version in the Cargo.toml

It would be really cool if the RLS (or the VSCode extension?) could quickly lookup the existing versions for a given package and propose the most recent one as auto-completion.

Would this be an appropriate feature for the RLS? And is this possible to implement within the current code base?

This would be very cool indeed! I think it currently lies out of scope of rls functionality, a cargo-toml language server or ide-plugin could provide the functionality.

Though I do agree that it would be nice for such functionality to be provided for all rls users somehow.
