packages built from rust-rand-core 0.5 need to migrate to testing.
We have the following situation here:
- librust-rand-core-dev (=0.3.0-1)
* bullseye (testing):
- librust-rand-core-0.4-dev (= 0.4.2-1) with:
Provides: librust-rand-core-dev (= 0.4.2-1)
Breaks: librust-rand-core-dev (<< 0.4.3-~~)
* sid (unstable):
- librust-rand-core-dev (= 0.5.1-1)
So librust-rand-core-dev collides with the Breaks requirement, while not
having an updated version available in testing.
Our packaging scripts check that the latest non-semver-suffixed version
is packaged (here: 0.5.1), which is the case, but of course it can't
control when packages migrate.
The whole compound covering the librust-rand-* packages has undergone
significant refactoring upstream which was a bit tedious to update in
Debian. The rust-rand-core 0.5.1 packages should be able to migrate by
now, don't know why they didn't.
