  [1 out of 3 hunks FAILED -- saving rejects to file Cargo.toml.rej
error: Bad exit status from /var/tmp/rpm-tmp.oD8j1p (%prep)
    Bad exit status from /var/tmp/rpm-tmp.oD8j1p (%prep)]: [Here the build fails because one of the patches could not be applied.]

Issue: The build failed because 1 hunk patching the file Cargo.toml did not apply to the package source code.
Resolution: To fix this, the patch file needs to be changed to apply to the current package source code.
