Feature Request

Describe the Feature Request

Links in the docs to other structures/modules etc. should be linkable, so that if you click on them you can go to the definition seamlessly.

Example:

This feature is inspired by the scarb doc feature which does the same thing but in mdbook - you can look for this implementation in the reference.

Describe Preferred Solution

While marking the code with appropriate markers (i.e. [`std::path::Path`] ) we should display a link to the actual implementation or the docs (TBD)

I believe this PR is relevant code for scarb doc
