This bug should've been closed at some point in the past but has reappeared in the newer version:
cargo 1.70.0+dfsg2-1 rustc 1.70.0+dfsg2-1 rustc recommends cargo >= 0.71.0~~ and cargo < 0.72.0~~ … The expected solution to the problem (merging of the cargo and rustc sources) has already happened, so it seems that the thing needed now is some frobbing of substvars for the contol file based on the package version? An = versioned recommends based on the standard/automatic substvars? Exercise left to rust stakeholders to discuss. Joseph
