[Pkg-rust-maintainers] Bug#1034948: librust-digest-0.9-dev: missing Breaks+Replaces for librust-digest-dev when upgrading from bullseye

[Helmut Grohne]

Package: librust-digest-0.9-dev
Version: 0.9.0-2
Severity: serious
Justification: dpkg unpack error

Attempting to unpack librust-digest-0.9-dev/0.9.0-2 from Debian bookworm
on a minimal Debian bullseye with librust-digest-dev/0.9.0-1
installed, causes an unpack error from dpkg due to
/usr/share/cargo/registry/digest-0.9.0/.cargo-checksum.json being contained in both packages.

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