How does Rust handle concurrency, and what mechanisms does it employ to ensure thread safety?

Rust's approach to concurrency is designed to provide a high level of safety without sacrificing performance. The language incorporates a set of ownership and borrowing rules, along with specific constructs, to manage concurrent access to data and prevent common pitfalls such as data races. The key mechanisms Rust employs for concurrency and thread safety are: Ownership System: 1. Ownership Rules: - Rust's ownership system ensures that each value has a unique owner. - Ownership can be transferred between variables but is never shared concurrently between threads unless explicitly managed. 2. Send and Sync Traits: - Types in Rust are classified into `Send` and `Sync` traits. - `Send` indicates that ownership of the type can be transferred safely between threads. - `Sync` indicates that references to the type can be safely shared between threads. Borrowing and References: 1. Immutable Borrowing: - Multiple threads can....
