Description
What do you want?
When hovering over crate names in Cargo.lock and Cargo.toml, I'd like a link to docs for that crate, with an embedded short description. Note that this already works within .rs files; simply hover over the crate name of an import.
Ideally, this should link to the version that I'm actually relying on.
Why do you want this?
When getting familiar with new code bases, it can be challenging to understand what various crates are used for. Being able to skim these all together would be very helpful and reduce the need to leave comments explaining what dependencies are for.

Research direction
Start by comparing the existing crate-name hover behavior in .rs files with hover handling for Cargo.lock and Cargo.toml. Determine where dependency versions and crate descriptions are available; done means hovering a crate in both manifest files shows a short description and links to the relied-on crates.io version.
