A Bitboard-based shogi library in Rust. Board representation, move generation/validation and time control utilities.
A library for implementing Shogi application.
shogi provides a various types and implementations for representing concepts and rules in Shogi.
Most types can be created programatically while they can also be deserialized from / serialized to SFEN format.
See USIプロトコルとは (What is the USI protocol?) for more detail about UCI protocol specification and SFEN format.
