Error raised on workspace inheritance of package.edition

[cat-in-136]

"value from workspace hasn't been set" error raised when workspace inheritance is used and its toml has package.edition.

#44 (comment)

@cat-in-136 Did some testing. When I use the workspace for the version / license it works fine. But adding the edition, will result in the above error. First gut feeling is that somethings is going wrong in the toml_edit lib, as the generate-rpm code is not using the edition field. That would suggest things go wrong on line 73: manifest.inherit_workspace(&workspace_manifest, p.as_ref())?;, some context to the errors would help.

It is caused by the cargo_toml bug https://gitlab.com/crates.rs/cargo_toml/-/issues/20

@Christiaan676 I wrote a workaround code referring to bnjbvr/cargo-machete@096df04 :

Could you please confirm my cargo_toml_20_hack branch? If it is sufficient for your project, I would like to merge this change.

@cat-in-136 The fix works for me. Thanks for applying the workaround!
