[Pkg-rust-maintainers] Bug#979184: rust-lazycell: newly introduced binary packages uninstallable.

[plugwash]

Package: rust-lazycell
Version: 1.3.0-1
Severity: serious

The upload of rust-lazycell 1.3.0-1 introduced three new binary 
packages, two of which are currently
uninstallable. This is preventing the package from migrating to testing 
which is annoying the release
team (see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977583 )

I believe that the "nightly-testing" and "clippy" features should simply 
be dropped, both of them
appear to me to be related to linting the package with clippy rather 
than actual runtime features.

If noone objects I will make an upload dropping these features in a week 
or so.
