<h2>Green Energy Language</h2>
<img src="_images/rust-energy-full.png" alt="">
<aside class="notes">
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"
