The run-time speed and memory usage of programs written in Rust should about the same as of programs written in C, but overall programming style of these languages is different enough that it's hard to generalize their speed. This is a summary of where they're the same, where C is faster, and where Rust is faster. Disclaimer: It's not meant to be an objective benchmark uncovering indisputable truths about these languages. There's a significant difference between what these languages can achieve ...
