Crate polyglot_book_rs 

polyglot-book-rs

A Rust library for reading and using Polyglot opening book format for chess engines.

This library provides functionality to:

• Load Polyglot opening book files (.bin format)
• Query moves from positions using FEN strings
• Query moves from positions using custom Board implementations
• Access move weights and statistics

Quick Start

use polyglot_book_rs::PolyglotBook;

// Load a book file
let book = PolyglotBook::load("book.bin").expect("Failed to load book");

// Query by FEN string
let starting_position = "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1";
if let Some(entry) = book.get_best_move_from_fen(starting_position) {
    println!("Best move: {} (weight: {})", entry.move_string, entry.weight);
}

Re-exports
