[Pkg-rust-maintainers] Bug#1034994: librust-semver-0.9-dev: missing Breaks+Replaces for librust-semver-dev when upgrading from bullseye

[Helmut Grohne]

Package: librust-semver-0.9-dev
Version: 0.9.0-3+b1
Severity: serious
Justification: dpkg unpack error

Attempting to unpack librust-semver-0.9-dev/0.9.0-3+b1 from Debian bookworm
on a minimal Debian bullseye with librust-semver-dev/0.9.0-1+b1
installed, causes an unpack error from dpkg due to
/usr/share/cargo/registry/semver-0.9.0/.cargo-checksum.json being contained in both packages.

Please ensure that librust-semver-0.9-dev has sufficient Breaks and Replaces declarations.
