How do Rust and C compare in terms of compiler optimizations?

Rust and C both have powerful compiler optimizations, but they approach them differently due to their language features.

What specific optimizations does the Rust compiler perform?

The Rust compiler, primarily through LLVM, performs optimizations like inlining, dead code elimination, and loop unrolling.

Are there any optimizations that C compilers do better than Rust?

C compilers often have more mature optimization techniques due to their longer history, especially for low-level hardware access.

How does memory safety in Rust affect its optimizations?

Memory safety in Rust can introduce some overhead, but it also allows for more aggressive optimizations since the compiler can guarantee certain properties.

Which language is generally faster after optimizations, Rust or C?

It depends on the specific use case, but C often has a slight edge in raw performance due to its lower-level nature.
