Building package from local modified sources

[TLATER]

Now it is failing on .cargoHash mismatch. Asking to set .cargoHash=”” to find the actual hash. Which I do but it is not making any difference, still getting the same error about .cargoHash mismatch and still being asked to set .cargoHash=””.

Yes, with rust things are different because the cargo vendor dir is built differently. .overrideAttrs doesn’t work ootb.

You have to separately override the source for the cargo vendor dir. See this thread: Is it possible to override cargoSha256 in buildRustPackage?
