Ntọhapụ nke asụsụ mmemme usoro Rust 1.57, nke Mozilla ngo tọrọ ntọala, ma ugbu a, nke e mepụtara n'okpuru nkwado nke otu nọọrọ onwe ya na-abụghị uru Rust Foundation, ka ebipụtara.

- Emeela ka ojiji nke nnukwu “ụjọ” ahụ kwụsie ike. n'ọnọdụ ndị emepụtara n'oge nchịkọta, dị ka nkwupụta "const fn". Ọzọkwa, na mgbakwunye na iji "egwu!" nkwupụta const na-enye ohere iji nnukwu nnukwu "nkwado!" yana ụfọdụ API ọba akwụkwọ ọkọlọtọ ndị ọzọ. Nkwụsi ike ekpuchibeghị akụrụngwa nhazi niile, yabụ n'ụdị ya ugbu a, nnukwu “egwu!” enwere ike iji naanị eriri static (ụjọ!
