Support for path dependencies

[bbigras]

I have some dependencies like this:

mydep = { path = "/some/path" }

cargo-vendor doesn't seem to include them in the vendor directory. Normally it's not needed except when using Docker.

Note that Cargo itself doesn't have support for this, so this would likely need to be implemented there first.

cargo-vendor is nice with Docker to not have to re-download everything but we still need to recompile everything. If caching is the solution to that maybe I don't need support for path dependencies.

[alexcrichton]

Oh so typically path dependencies are idiomatically within the same "repository" or working-directory ish, when using path dependencies across the filesystem and/or other repos you'll typically want to use something like [replace] or git dependencies instead.

What about support path now?

Cargo supports path-relative dependencies, but cargo vendor doesn't @alexcrichton . This means I can't use a Dockerfile to create a docker image of a project I'm working on if that project isn't published in git or crates.io. There are hacky workarounds, but it would be great if vendor worked on paths.

This crate is now included natively in Cargo as of rust-lang/cargo#6869 and today's nightly Rust. I'm closing all issues in this repository before I archive the repository, but if you're still interested in seeing this issue fixed then please feel free to file an issue with Cargo itself!
