Rust Foundation avaldas statistikat, mille kohaselt kasutab 127 000 m\u00e4rkimisv\u00e4\u00e4rse paketi, mis on esitatud crates.io kataloogis, \u00fcle 24 000 (19,11%) m\u00e4rks\u00f5na \u201eunsafe\u201d m\u00e4lu haldamiseks ohtlike v\u00f5imaluste lubamiseks teatud koodiplokkides, nagu n\u00e4iteks viidatud n\u00e4itajate de-referentsimine, v\u00e4liste funktsioonide kutsumine v\u00f5i staatichete muutmine. 34,35% pakettidest kutsub otse funktsioone teistest crate-pakettidest, milles kasutatakse re\u017eiimi \u201eunsafe\u201d. <\/p>\n

Tuleb m\u00e4rkida, et enamikul juhtudel on re\u017eiimi \u201eunsafe\u201d kasutamine seotud kodeerimisega, mis on loodud teistes keeltes v\u00f5i C\/C++-i teekide k\u00f5netega. K\u00f5ige rohkem \u201eunsafe\u201d k\u00f5nesid sisaldav pakett on Microsofti arendatud crate-pakett windows, mis on Windowsi platvormi API \u00fcmber tasuta. Sellel paketil on 36 miljonit allalaadimist. Unsafe'i kasutatakse ka k\u00f5ige populaarsemates pakettides syn (470 miljonit allalaadimist), proc-macro2 (354 miljonit allalaadimist) ja libc (345 miljonit allalaadimist). <\/p>\n

Probleemide tuvastamiseks koodis, mis t\u00f6\u00f6tab re\u017eiimis \u201eunsafe\u201d, arendatakse projekti raames interpreteerijat Miri, mis v\u00f5imaldab tuvastada juurdep\u00e4\u00e4su puutumatutele aladele, m\u00e4lu kasutamise p\u00e4rast vabastamist, vale kasutamise mittealgatatud andmete osas, p\u00f5hiliikide invariantide rikkumist (nt bool-vaheliste vastavuste 0 v\u00f5i 1 osas), objektide omandireeglite rikkumist, olukordade \u00f5hkkonna tekkimist ja m\u00e4lu leket.
