22.10 Comparing Rust's Tools to C/C++ (e.g., OpenMP)
In C and C++, concurrency often relies on:
- Threads: Pthreads on POSIX systems or
<thread>in modern C++. - OpenMP: A directive-based model that can parallelize loops.
In contrast, Rust's compiler enforces thread safety through the type system, preventing many concurrency bugs (e.g., data races) at compile time. Libraries like Rayon offer a data-parallel approach akin to OpenMP but with additional safety guarantees due to Rust's borrowing and ownership rules.
