Crate usi

Types representing commands defined in USI protocol.

USI protocol defines commands sent from either GUIs or engines. Detail about USI protocol is found at http://www.geocities.jp/shogidokoro/usi.html.

Examples

use std::time::Duration;
use usi::{GuiCommand, ThinkParams, EngineCommand, BestMoveParams};

// GuiCommand can be converted into the USI compliant string.
let params = ThinkParams::new().btime(Duration::from_secs(1)).wtime(Duration::from_secs(2));
let cmd = GuiCommand::Go(params);
assert_eq!("go btime 1000 wtime 2000", cmd.to_string());

// EngineCommand can be parsed from the command string sent from the USI engine.
let cmd = EngineCommand::parse("bestmove 7g7f ponder 8c8d").unwrap();
match cmd {
    EngineCommand::BestMove(BestMoveParams::MakeMove(ref m, Some(ref pm))) => {
        assert_eq!("7g7f", *m);
        assert_eq!("8c8d", *pm);
    },
    _ => unreachable!(),
}
