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. Sebaka sa polokelo se tšehetsoa ho amohela lilaebrari crates.io.

Lengolong la phatlalatso ea tokollo e ncha, baetsi ba Rust ba ile ba kenella lipolotiking 'me ba hana ka ho hlaka ho phatlalatsa tlhahlobo e feletseng ea liphetoho tsa Rust 1.44 e le pontšo ea bonngoe le baipelaetsi khahlanong le pefo ea mapolesa, e bontšang hore taba ena ke ea bohlokoa haholo. hofeta phapanyetsano ya tsebo ya botekgeniki. Motheo boiqapelo:

• Motsamaisi oa sephutheloana sa Cargo o kopanya taelo ea "cargo tree", e bonts'ang kerafo e ts'oanang ea ho itšetleha ka sefate. Hape ke khetho ea "-duplicates" ("cargo tree -d"), e leng se u lumellang hore u hlahlobe ho itšetleha ka mefuta e fapaneng ea sephutheloana se le seng.
