This module provides a pretty straightfoward interface for converting Forsyth-Edwards notation (FEN) into the state of a game of chess and back.
FEN is a way of representing a board a string. This crate provides one such
representation, fen::BoardState. If you want to be able to read FEN, you
will to need to create a way to convert BoardState to your own board
representation. If you want to export FEN, you will need to convert your
own board representation to BoardState.
