[ The Jimi Hendrix Experience [1] Little Wing,

a free open source chess engine by Vincent Ollivier, written in Rust, supporting the Chess Engine Communication Protocol as well as UCI, distributed under the terms of the GNU General Public License version 3. Little Wing is work in progress started in December 2014 [2]. As bitboard engine, Little Wing relies on Rust primitive type u64 [3], which also features trailing zero count [4], and population count [5]. So far, sliding piece attacks - even for single pieces - are computed by a generalized loop fill along the rays [6].
