where .cargo/config.toml should be located

[uncomfyhalomacro]

Based on my observation obs-service-cargo will generate .cargo/config.toml at the root of the project directory. This comes with some caveats that we have to do that --manifest-path=<path-to-Cargo.toml> as an additional flag on the specfile. This is not ideal.

So based on https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure, I should

• If it's a workspace configuration, use the workspace Cargo.toml's location as the location for the .cargo/config.toml
• Otherwise, we should put .cargo/config.toml for each location of the Cargo.toml for each crate found or used.

Relevant openSUSE package: monorepo-like Rust package such as python-tokenizers

Additionally, vendor seems to not extract at the exact path. Is this caused by the change when we merged a PR that modifies mtime in the tarball for reproducible builds

I remembered i designed this in a way where if it is extracted, they're extracted in the correct path... (i might be wrong so imma investigate this lol)

TODO

• Investigate Fix #64: Make tarballs reproducible #78
  • Fix pathing. (Investigate and add findings)
  • Fix extracting. (Investigate and add findings)
• Add tests
  • Monorepo packages e.g. python-tokenizers
  • Workspaces e.g. wezterm, zellij
