What is faster C or Rust?

To sum it up. Rust is low-level enough that if necessary, it can be optimized for maximum performance just as well as C . Higher-level abstractions, easy memory management, and abundance of available libraries tend to make Rust programs have more code, do more, and if left unchecked, can add up to bloat.

Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages.

It’s quite difficult to say which language is faster because it depends on case to case. But we can say that Rust is a competitor of C in terms of speed and it is faster than many other popular languages like Java and Python.
