Uzupe\u0142nienie: Firma Google og\u0142osi\u0142a swoje uczestnictwo w inicjatywie na rzecz promowania wsparcia dla Rust w j\u0105drze Linux i przedstawi\u0142a aspekty techniczne zasadno\u015bci wdro\u017cenia Rust w celu rozwi\u0105zania problem\u00f3w zwi\u0105zanych z b\u0142\u0119dami w zarz\u0105dzaniu pami\u0119ci\u0105.

W artykule przedstawiono r\u00f3wnie\u017c przyk\u0142ady u\u017cycia j\u0119zyka Rust do tworzenia sterownik\u00f3w j\u0105dra w kontek\u015bcie ich wykorzystania na platformie Android (Rust zosta\u0142 oficjalnie uznany za wspierany j\u0119zyk do tworzenia aplikacji na Android). <\/p>\n

Zauwa\u017cono, \u017ce Google przygotowa\u0142 wst\u0119pny prototyp sterownika napisanego w j\u0119zyku Rust dla mechanizmu mi\u0119dzyprocesowego Binder, co umo\u017cliwi szczeg\u00f3\u0142owe por\u00f3wnanie wydajno\u015bci i bezpiecze\u0144stwa implementacji Binder w C i Rust. W obecnym stanie prace jeszcze nie zosta\u0142y zako\u0144czone, ale prawie dla wszystkich podstawowych abstrakcji funkcjonalno\u015bci j\u0105dra, niezb\u0119dnych do dzia\u0142ania Binder, przygotowano przystawki do wykorzystania tych abstrakcji w kodzie napisanym w j\u0119zyku Rust.
