Rust is often called one of the most 'energy efficient' programming languages. Benchmarks of serverless applications on various cloud platforms showed that Rust beats other languages in terms of the cold start time (<200ms) and execution time due to the low-level nature. This allows developers to create fast and computationally intensive applications in serverless architecture and gives users a better experience by eliminating a "cold start problem". It would be awesome if DigitalOcean adopted this programming language in their products!
