I’m encountering the error below, which claims that
serde_derive is not found in a crate that I’m depending on (which I also wrote). That crate builds just fine on its own, and does not use any features. Any ideas what might be going wrong, or how to debug this? I’m not even sure how to reproduce the build that is failing.
