Sakin Rust 1.94. Gwaji da Tsatsa a cikin FreeBSD Kernel. Turso Database da VCAD a cikin Rust

Yaren shirye-shirye na Rust 1.94, wanda aikin Mozilla ya kafa amma yanzu an haɓaka shi a ƙarƙashin inuwar Rust Foundation mai zaman kanta, mai zaman kanta. Harshen yana mai da hankali kan amincin ƙwaƙwalwar ajiya kuma yana ba da kayan aikin don cimma babban daidaici na aiwatar da aikin, yayin yin ba tare da yin amfani da mai tara shara da lokacin aiki ba (an rage lokacin aiki zuwa farawa na asali da kiyaye daidaitaccen ɗakin karatu).
