gpg packages need to be installed despite pgp feature not enabled

[djmaze]

Just tried to compile my app against the latest master (on NixOS). Had to gnupg and gpgme although I do not have pgp-* features enabled in my Cargo.toml.

• The flake.nix from the current repository does not link Cargo features with Nix, this could definitely be a nice improvement.
• That said, the current version on nixpkgs does the link, could you share your Nix code?

I would advise not to use actual versions on repositories because they are not up-to-date (due to the beta). The v1.0.0 is being tested on master, which I would recommand to use instead.

I am building my own app which uses the email-lib crate (latest master) with a custom (non-flake) shell.nix. But I think it does matter. I just want to propose that it should be possible to use the email-lib crate without the gpg dependencies, as the pgp-* features are already optional in the codebase.

Yes I agree, I just have no idea how to do with nix flakes. Last time I searched, it was not possible to pass arguments to the nix build.
