Hikaru
Hikaru provides Rust bindings to the Chess.com API, specifically for downloading all of a player's games. It is named after Grand Master Hikaru Nakamura (unless he objects, in which case I'll change the name). JSON parsing is done via SereE; reqwest is used to get data from the API.
How to Use
All you have to do is feed Hikaru a list of usernames, and you get back a Vec<[GameData]>
use GameData;
let user_names = vec!;
let games = download;
// Check out Hikaru's first game on Chess.com:
dbg!;
Future plans
Create a stockfish wrapper so that you can analyze all your games. The game data include all the moves made in those games, so this can be fed into the engine for a variety of analyses.
