Num estudo sobre quais linguagens consomem mais
|
||
|
|
energia, Rust chegou bem próximo de C.
|
||
|
|
|
||
|
|
Parte do trabalho de otimização do Rust vem da LLVM
|
||
|
|
(parte do pacote do Clang), mas a árvore de
|
||
|
|
abstração ainda é gerada pela linguagem -- o que
|
||
|
|
significa que o compilador Rust consegue "ajudar" o
|
||
|
|
LLVM a otimizar o código.

"Speaking of languages, it's time to halt starting any new
|
||
|
|
projects in C/C++ and use Rust for those scenarios
|
||
|
|
where a non-GC language is required. For the sake of
|
||
|
|
security and reliability. the industry should declare
|
||
|
|
those languages as deprecated"
