Want to run the code?

One of the goals with this repo is to experiment and compare different implementations of the same algorithm. You can run the analysis by using cargo run and you can choose the analysis with -a. So for example to run against an example extract from clap, you might do:

> cargo +nightly run --release -- -a DatafrogOpt inputs/clap-rs/app-parser-{{impl}}-add_defaults/
    Finished release [optimized] target(s) in 0.05 secs
     Running `target/release/borrow-check 'inputs/clap-rs/app-parser-{{impl}}-add_defaults/'`
--------------------------------------------------
Directory: inputs/clap-rs/app-parser-{{impl}}-add_defaults/
Time: 3.856s

You could also try -a Naive to get the naive rules (more readable, slower) -- these are the exact rules described in the blogpost. You can also use -a LocationInsensitive to use a location insensitive analysis (faster, but may yield spurious errors).

By default, cargo run just prints timing. If you also want to see the results, try --show-tuples (which will show errors) and maybe -v (to show more intermediate computations). You can supply --help to get more docs.
