Rust Foundation on avaldanud statistikat, mille kohaselt 127 000 olulisest paketist, mis on esitatud crates.io kataloogis, kasutab \u00fcle 24 000 (19,11%) m\u00e4rks\u00f5na \u201eunsafe\u201c funktsioonide lisamiseks, mis v\u00f5imaldavad m\u00e4lu puudulikku t\u00f6\u00f6tlemist teatud koodiplokkides, nagu n\u00e4iteks n\u00e4idikute dereferentseerimine, v\u00e4listest funktsioonidest \u00fcleskutsete tegemine v\u00f5i staatiliste muutujate muutmine. 34,35% pakettidest teeb otsekutseid funktsioonidest teistest crate-pakettidest, milles kasutatakse \u201eunsafe\u201c re\u017eiimi. <\/p>\n

T\u00e4heldatakse, et enamikul juhtudel on \u201eunsafe\u201c re\u017eiimi kasutamine tingitud kodeerimisest, mis on kirjutatud teistes keeltes v\u00f5i raamatukogudest C\/C++ keeles. Paketist, millel on k\u00f5ige rohkem \u201eunsafe\u201c re\u017eiimi \u00fcleskutsed, on Microsofti arendatav crate-pakett windows, mis on Windows API \u00fcmbris. See pakett on saanud 36 miljonit allalaadimist. Unsafe'i kasutatakse ka k\u00f5ige populaarsemates pakettides, nagu syn (470 miljonit allalaadimist), proc-macro2 (354 miljonit allalaadimist) ja libc (345 miljonit allalaadimist). <\/p>\n

Probleemide tuvastamiseks \u201eunsafe\u201c re\u017eiimis k\u00e4ivas koodis arendatakse projekti raames t\u00f5lgendajat Miri, mis v\u00f5imaldab tuvastada piire \u00fcletavaid viiteid, m\u00e4lu kasutamist p\u00e4rast vabastamist, mitteinitsialiseeritud andmete vale kasutamist, p\u00f5hity\u00fcpide invariantide rikkuvust (n\u00e4iteks booli vastavus v\u00e4\u00e4rtustele 0 v\u00f5i 1), objektide valdamise reeglite rikkumist, v\u00f5idus\u00f5idust tingitud seisundeid ja m\u00e4lulekkeid.
