Hi!

While rebuilding the python related packages for the Python 3.15 transition,
we found that python-maturin fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/5165817/

From the log, the error seems to be:

    missing:
     pkg:
      package: sbuild-build-depends-main-dummy
      version: 0.invalid.0
      architecture: amd64
      unsat-dependency: librust-cargo-options-0.7+default-dev:amd64 (>= 0.7.2)

This is because there's a new rust-cargo-options package, version 0.8.1, so it
no longer provides the 0.7 version:
https://tracker.debian.org/pkg/rust-cargo-options

We believe that the bug you reported is fixed in the latest version of
python-maturin, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1151054@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
