Rust (programmeringssprog)

For alternative betydninger, se Rust (flertydig). (Se også artikler, som begynder med Rust)

Rust er et multi-paradigme programmeringssprog skabt af Graydon Hoare, der er omhyggeligt designet til at levere høj ydeevne og it-sikkerhed.

Sproget er særligt kendt for sin evne til at håndtere samtidighed på en sikker måde, hvilket minimerer risikoen for kørselsfejl. Rust svarer syntaktisk til C og C++, men kan garantere hukommelsessikkerhed ved at bruge en lånekontrol til at validere referencer. Man kan dog komme uden om dette ved f.eks. at bruge et såkaldt 'unsafe' keyword, hvilket giver mere fleksibilitet, men også øger programmørens ansvar for korrekt hukommelsesstyring, da det tillader kode, der potentielt kan bryde hukommelsessikkerheden ^[1].

Ifølge Google-udviklere er Rust bedre end C++ og Go, da udviklerne bliver dobbelt så effektive.^[2]

2. ^ 31 Mar 2024, theregister.com: Rust developers at Google are twice as productive as C++ teams. Code shines up nicely in production, says Chocolate Factory's Bergstrom, backup Citat: "..."When we've rewritten systems from Go into Rust, we've found that it takes about the same size team about the same amount of time to build it," said Bergstrom. "That is, there's no loss in productivity when moving from Go to Rust. And the interesting thing is we do see some benefits from it. "So we see reduced memory usage in the services that we've moved from Go ...and we see a decreased defect rate over time in those services that have been rewritten in Rust – so increasing correctness."..."In every case we've seen a decrease by more than 2x in the amount of effort required to both build the services in Rust as well as maintain and update those services written in Rust," he said...A bit more than half of his developers say that Rust is easier to review, according to Bergstrom..."
