Rust forces you to draw safety boundaries between safe and unsafe code, but you can do almost strictly more than C in unsafe Rust. It has support for inline assembly, SIMD, packed structs, and well-defined signed integer overflow. None of these is part of standard C or C++, and is only available through compiler-specific dialects. There wasn't even a well-defined memory model with support for atomics before C11/C++11.
