Zbus / Nix Dependency Issue

[nadenf]

So there is an odd situation where Zbus has a dependency on Nix but didn't correctly specify it whereas some other library did which has now removed it.

Which in turn is causing Notify (latest version 4) to not compile on Ubuntu Linux with the following error:

error[E0432]: unresolved import `nix::unistd::Uid`
  --> /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/zbus-3.14.1/src/address.rs:9:5
   |
   | use nix::unistd::Uid;
   |     ^^^^^^^^^^^^^^^^ no `Uid` in `unistd`
   |
note: found an item that was configured out
  --> /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/nix-0.26.4/src/unistd.rs:73:12
   |
   | pub struct Uid(uid_t);
   |            ^^^
   = note: the item is gated behind the `user` feature

There is a PR here which fixes it but you may want to temporarily fix this.

Reddit thread which is discussing this issue as it affects other libraries as well.

Does that even affect notify? It sounds more like users of zbus have to upgrade such that the relevant feature is selected.

Closing this. It was showing up as a dependency in Cargo.lock but must a transitive one.
