Backend API to be hosted at api.worldrank.org

Make sure that the path_to_data directory specified in configuration/base.yml contains all_players.csv, all_contests.csv, and all the files players/{handle}.csv. See the parent directory for the command that creates these.

After installing Rust, build and run the program with:

cargo run --release

Now you can access the API from another terminal or application. Examples:

curl http://127.0.0.1:8000/top -d "source=codeforces&start=0&many=10"
curl http://127.0.0.1:8000/count -d "source=codeforces"
curl http://127.0.0.1:8000/count -d "source=codeforces&min=1400&max=1599"
curl http://127.0.0.1:8000/player -d "source=codeforces&handle=EbTech"
curl http://127.0.0.1:8000/autocomplete -d "source=codeforces&query=EbTec&many=10"
