Mwepụta asụsụ mmemme nchara 1.60

Mwepụta nke asụsụ mmemme izugbe nke Rust 1.60, nke ọrụ Mozilla hiwere, mana nke emepụtara ugbu a n'okpuru nkwado nke otu nọọrọ onwe ya na-abụghị uru Rust Foundation, ka ebipụtala. Asụsụ ahụ na-elekwasị anya na nchekwa nchekwa ma na-enye ụzọ iji nweta ọrụ dị elu na parallelism ma na-ezere iji onye na-ekpofu ihe mkpofu na oge ịgba ọsọ (oge ọ na-agba ọsọ na-ebelata ka ọ bụrụ mmalite na nhazi nke ọbá akwụkwọ ọkọlọtọ).

Ụzọ ijikwa ebe nchekwa rust na-azọpụta onye nrụpụta site na njehie mgbe ị na-emegharị ihe nrịbama ma chebe onwe ya pụọ ​​​​na nsogbu ndị na-ebilite n'ihi njikwa ebe nchekwa dị ala, dị ka ịnweta ebe nchekwa mgbe a tọhapụrụ ya, iwepụ pointers null, buffer overruns, wdg. Iji kesaa ọba akwụkwọ, nye ihe na-ewuli elu ma jikwaa ịdabere, ọrụ ahụ na-emepụta onye njikwa ngwugwu Cargo. A na-akwado ebe nchekwa crates.io maka ọba akwụkwọ nnabata.

A na-enye nchekwa nchekwa na nchara n'oge a na-achịkọta site na ntụle ntụnye aka, idobe usoro nwe ihe, idobe oge ndụ ihe (scopes), na ịlele izi ezi nke ịnweta ebe nchekwa n'oge mmebe koodu.
