What are the different threading models in Rust?
Rust primarily offers two threading models: the native OS threads and the green threads provided by libraries like Tokio.
Can you explain how native OS threads work in Rust?
Native OS threads in Rust are managed by the operating system, allowing for true parallelism. Each thread can run on a separate CPU core.
What about green threads? How do they differ?
Green threads are managed by a runtime library, like Tokio, which allows for lightweight concurrency. They are more efficient for I/O-bound tasks.
Which model is better for performance?
It depends on the use case. Native threads are better for CPU-bound tasks, while green threads excel in I/O-bound scenarios.
