Now I know why my previous suggestion doesn’t work. The src taken by cargoDeps doesn’t update when the main src is overridden. Thank you for testing and pointing out the issue.
I’m authoring a fix in Nixpkgs PR 435239. Please take a look!
master ← ShamrockLee:build-rust-package-overriding-pre
opened 11:40AM - 20 Aug 25 UTC
…riding
Make <rust-package>.cargoDeps reference the overridden <rust-package>… .src and other attributes.
Make Rust package overriding *possible* before making further design decisions about the `<pkg>.overrideAttrs` interface.
This is an initial effort to fixe #415397
