RFE: add option to specify path to Cargo.lock (original) (raw)

In Fedora we package all crate sources (including tests) in /usr/share/cargo/registry which is not user-writable. However, we would like to run tests for them after installation. There is already option for target-dir and it would be very nice to get option to put Cargo.lock in some other directory so that we could run cargo test from there.
