<h2>Green Energy Language</h2> |

||||
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" |
