[Pkg-rust-maintainers] Preliminary version of debcargo published

[Willem Mali]

That's great to hear, and I would like to volunteer on dh-cargo. Can I get
started on an /bin/sh -eu based dh-cargo, and is it OK to use that language?

If you want a rough idea of what my scripting currently looks like, this
would be most representative:

> - For lib crates, run "cargo package" in the build target, and extract

>   /usr/share/rust/cargo/$crate-$version in the binary target, to add it
>   to the cargo directory registry.  In that same directory, write a
>   .cargo-checksum.json file containing
>   `{"package":"$checksum","files":{}}` , where $checksum is the
>   sha256sum of the .crate file.
> - For bin crates, run "cargo install --path . --root $tmpdir" in the
>   binary target, where $tmpdir refers to the directory you package the

> replace-with = 'debian-registry'
> local-registry = "/nonexistent"
>
> [source.debian-registry]
> directory = '/usr/share/rust/cargo'

> dh-cargo's job easier (such as by pre-determining the list of binary and
> library crates and providing that to dh-cargo somehow so it doesn't need
> to parse debian/control).
