// When we test our cfg machinery, in crates/arti/src/cfg.rs, we need to know
// which cargo features are enabled - not just in the arti crate, but in the dependencies.
// Indeed, we want to test with precisely the features we intend.
// However, cargo feature unification can mean that features are enabled in dependencies,
// even if *we* (arti) don't request them - especially if we run with --workspace.
//
// This `--cfg` is passed by maint/test-all-crates, when we test each crate individually.
// That tells our test cases in cfg.rs that they can check that a feature is
// actually unsupported.
//
// (We don't want this to be a normal cargo feature because then it would be enabled
// with --workspace --all-features, defeating the point.)
//
// NOTE: This was previously used by memquota which was behind a feature flag. Now that we
// always build arti with support for memquota, this is unused. But leaving it in place for now
// anyways in case we want it again in the future.
