kuburitsa 1.47 yemutauro wepurogiramu yemutauro , yakatangwa neMozilla project. Mutauro unotarisana nekuchengetedza ndangariro, unopa otomatiki ndangariro manejimendi, uye inopa nzira yekuwana yakakwirira basa parallelism pasina kushandisa ΠΈ (nguva yekumhanya inodzika kusvika kukutanga kwekutanga uye kugadzirisa raibhurari yakajairwa).
Rust's otomatiki ndangariro manejimendi inobvisa zvikanganiso kana ichishandisa anongedza uye inodzivirira kubva kune yakaderera-level memory manipulation, sekuwana nzvimbo yekurangarira mushure mekunge yasunungurwa, null pointer dereferences, buffer overruns, nezvimwe. Maneja wepakeji ari kugadzirwa kugovera maraibhurari, kuona kuungana uye kugadzirisa zvinovimbika neprojekiti. . A repository inotsigirwa kuitisa maraibhurari .
chikuru :
- Inoshandiswa tsigiro yemhando chero saizi. Kare, nekuda kwekusakwanisa kutsanangura mabasa egeneric kune ese akaenzana kukosha, raibhurari yakajairwa yakapa yakavakirwa-mukati tsigiro yehunhu chete kune arrays anosvika makumi matatu nemaviri muhukuru (hunhu hwesaizi yega yega hwaitsanangurwa statically). Nekuda kwekugadzirwa kwekushanda kweanogara achigadzirwa ("const generics"), zvakave nyore kutsanangura mabasa egeneric kune chero saizi yemhando, asi haasati abatanidzwa mune yakagadzikana maficha emitauro, kunyangwe iwo anoitwa mumubatanidzwa uye ari. ikozvino muraibhurari yakajairika yemhando dzemhando ipi neipi.
Semuenzaniso, iyo inotevera kuvaka muRust 1.47 ichadhinda zviri mukati mehurongwa, kunyangwe kare zvaizokonzera kukanganisa:
fn chikuru() {
rega xs = [0; 34];println!("{:?}", xs);
} - Inopihwa kuburitsa kweapfupi trace (backtrace), inobuda mumamiriro e emergency. Zvinhu zvisingafadzi mumamiriro mazhinji, asi zvinokanganisa zvinobuda uye zvinokanganisa kutarisa kubva kune izvo zvinokonzeresa dambudziko, hazvibatanidzwe kubva mukutsvaga. Kuti udzosere tsvakiridzo yakazara, unogona kushandisa shanduko yenharaunda "RUST_BACKTRACE=yakazara". Somuenzaniso, nokuda kwekodhi
fn chikuru() {
kutya!();
}Kare, tsvakiridzo yaibuda mumatanho makumi maviri nematatu, asi ikozvino ichaderedzwa kusvika
