Crate fen4

Fen4 provides a mapping from a simple representation of a 4 player chess board and the fen4 file format used by Chess.com.

Quick Start

The Board struct is the important type in this crate. All other types are present to support all the features of Board. The most common ways to get a Board would be via FromStr or Default.

let empty_fen = "R-0,0,0,0-0,0,0,0-0,0,0,0-0,0,0,0-0-14/14/14/14/14/14/14/14/14/14/14/14/14/14";
let board :  Result<fen4::Board,fen4::BoardParseError> = empty_fen.parse();
println!("{}",board?);
