Ho lokolloa ha puo ea lenaneo la tsamaiso Rust 1.57, e thehiloeng ke morero oa Mozilla, empa hona joale e ntlafalitsoe ka tlas'a ts'ebetso ea mokhatlo o ikemetseng o sa etseng phaello Rust Foundation, e hatisitsoe. Puo e tsepamisitse maikutlo holim'a ts'ireletso ea mohopolo, e fana ka taolo ea memori ea othomathike, 'me e fana ka mekhoa ea ho fihlela ts'ebetso e phahameng ea ts'ebetso ntle le ho sebelisa pokello ea lithōle kapa nako ea ho sebetsa (nako ea ho sebetsa e fokotsehile ho qala le ho boloka laebrari e tloaelehileng).
Taolo ea memori ea othomathike ea Rust e felisa liphoso ha e tsamaisa lintlha le ho sireletsa khahlanong le mathata a bakoang ke ho qhekella ha memori ea boemo bo tlase, joalo ka ho fihlella sebaka sa memori kamora hore e lokolloe, li-null pointer dereferences, buffer overruns, jj. Ho aba lilaebrari, ho etsa bonnete ba ho kopanya le ho laola ba itšetlehileng ka bona, morero o nts'etsapele mookameli oa thepa ea thepa. Sebaka sa polokelo ea crates.io se tšehetsoa bakeng sa lilaebrari tse amohelang batho.
Litlhahiso tse ka sehloohong:
- Tšebeliso ea "panic!" macro e tsitsitse. maemong a entsoeng nakong ea pokello, joalo ka liphatlalatso tsa "const fn". Ho phaella moo, ntle le ho sebelisa "ho tšoha!" const declarations lumella tšebeliso ea "assert!" macro. le li-API tse ling tse tloaelehileng tsa laeborari. Ho tsitsisa ha ho so koahele lisebelisoa tsohle tsa sebopeho, ka hona, ka sebopeho sa eona sa hajoale "panic!" macro e ka sebelisoa feela ka likhoele tse tsitsitseng (panic!(“...")) kapa ka boleng bo le bong "&str" ha ho nkeloa sebaka (panic!("{}", a)), e lokelang ho lekanyetsoa feela ho kenya "{ }" ntle le ho fomata litlhare le mefuta e meng.

- Motsamaisi oa sephutheloana sa Cargo o lumella ts'ebeliso ea li-profiles tse nang le mabitso a ikhethileng, a sa felle ho "dev", "release", "test" le "bench".

- Ts'ebeliso ea try_reserve bakeng sa mefuta ea Vec, String, HashMap, HashSet le VecDeque e tsitsitse, e u lumellang ho boloka sebaka esale pele bakeng sa palo e itseng ea likarolo tsa mofuta o fanoeng e le ho fokotsa khafetsa ts'ebetso ea kabo ea memori le ho qoba. ho soahlamana nakong ya tshebetso ka baka la ho hloka mohopolo.
