Puo ea Rust programming 1.44 tokollo

e hatisitsoeng tokollo ea puo ea lenaneo la sistimi Mafome 1.44, e thehiloeng ke morero oa Mozilla. Puo e shebana le polokeho ea mohopolo, e fana ka taolo ea memori ea othomathike, hape e fana ka lisebelisoa tsa ho fihlela ts'ebetso e phahameng ea ts'ebetso ntle le ho sebelisa pokello ea lithōle le nako ea nako.

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. Motsamaisi oa liphutheloana o ntse a ntlafatsoa ho aba lilaebrari, ho netefatsa ho bokelloa le ho laola litšepe ka morero. thepa, ho u lumella ho fumana lilaebrari tse hlokahalang bakeng sa lenaneo ka ho tobetsa hanngoe feela.
