[ERROR] failed to parse manifest at `[ROOT]/foo/Cargo.toml`

Caused by:
  feature `different-binary-name` is required

  The package requires the Cargo feature called `different-binary-name`, but that feature is not stabilized in this version of Cargo ([..]).
  Consider adding `cargo-features = ["different-binary-name"]` to the top of Cargo.toml (above the [package] table) to tell Cargo you are opting in to use this unstable feature.
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#different-binary-name for more information about the status of this feature.
