Documentation on how to use cargo lib to find target directory

[iddm]

I want to create a external cargo subcommand. I've checked few existing external subcommands and they are using cargo, but very old one. I have tried to find any information about how can I use the cargo crate for, for example, finding target directory, but I was unable to find such information anywhere. After that I decided to find any information about the cargo crate but I could not: it does not exist it seems.

A few questions:

1. Why is it so?
2. How to find any information about it then?

Thanks for the report! The crate isn't really intended to work well with newbies unfortunately right now in the sense that little-to-no effort has been put in to make it such (not that it can't be).

PRs with docs however would be most welcome!

Does this mean Cargo's programmatic API is meant to be backwards compatible?

From #5955 (comment) and #5839 (comment), no, it's not.

Going to close this since I don't think we need an issue to track a specific API item.

For the past months, the Cargo team has been working on improving the API documentation. We moved parts of contributors docs to rustdoc (e.g., #11662, #11809, #11850), and added more intra-doc links (e.g., #11711, #12133).

For my personal interest, I'd like to see more high-level concepts get documented, such as Source and Resolver.

Thank you for the report anyway!
