config.toml is a project-level configuration. Cargo will only read the configuration from the current directory and up, and not in:

  • package directories in a workspace
  • package directories when --manifest-path is used

Use build.rs instead, which will be executed before the package is built and only apply the flags for the specific package. This allows mixing drivers and applications in a workspace while still invoking Cargo from the workspace root.

LGTM. What do you think, @nicholasbishop?

`config.toml` is a project-level configuration. Cargo will only read the
configuration from the current directory and up, and not in:

- package directories in a workspace
- package directories when `--manifest-path` is used

Use `build.rs` instead, which will be executed before the package is
built and only apply the flags for the specific package. This allows mixing
drivers and applications in a workspace while still invoking Cargo from the
workspace root.
