Please could cargo-debstatus be updated to cope with newer Rust
editions?

Thanks!

Hi

I struggled to reproduce this issue on my system running debian unstable:

My version of cargo-debstatus:

$ dpkg -l cargo-debstatus
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name            Version      Architecture Description
+++-===============-============-============-===================================================
ii  cargo-debstatus 0.5.2-2+b1   amd64        print dependency tree of
a Rust project using Cargo

steps I took to try to reproduce:

git clone git@github.com:pydantic/pydantic-core.git
cd pydantic-core/
cargo debstatus

and that worked as expected, I also tried building debstatus from
source without problems.

Could you explain in a bit more detail how you encountered the bug?

best regards

This looks suspiciously like an old version of rustc that predates the
2021 edition, which was released with 1.56.0, while oldstable aka 11/bullseye
has 1.48.0. Julian, what version of rustc were you using? And from where was it
installed?
