[Pkg-rust-maintainers] Bug#956393: rust-unicode-width: uninstallable featureset packages.

[peter green]

Source: rust-unicode-width
Version: 0.1.7-1
Severity: serious

librust-unicode-width+std-dev and librust-unicode-width+rustc-dep-of-std-dev are not installable as they depend on librust-rustc-std-workspace-std-1+default-dev which does not seem to exist in debian.

This is blocking the rust-unicode-width source package from migrating to testing, which in turn is holding up rust-cbindgen from getting back into testing.

googling seems to suggest that "rustc-std-workspace-std" is a "hack for the compilers own build system" and not something intended for general use.

Should these featureset packages simply be dropped?
