What are the concurrency models in Rust?

What are the concurrency models in Rust?

Rust primarily uses two concurrency models: message passing and shared state. Message passing involves sending data between threads, while shared state allows multiple threads to access the same data safely.

Can you explain how message passing works in Rust?

Sure! In Rust, message passing is typically done using channels. You can create a channel that allows one thread to send messages to another, ensuring that data is transferred safely without shared mutable state.

What about shared state? How does Rust ensure safety?

Rust uses ownership and borrowing rules to ensure safety with shared state. It enforces that only one mutable reference exists at a time, preventing data races and ensuring thread safety.

Are there any libraries in Rust that help with concurrency?

Yes, libraries like Tokio and Rayon provide powerful abstractions for asynchronous programming and parallelism, making it easier to work with concurrency in Rust.
