Rust error handling uses Result-based patterns with thiserror for custom error types and anyhow for application-level flexibility. This approach enforces explicit error propagation, ensuring robust safety by preventing silent failures during compilation.

Safe concurrency in Rust uses Arc<Mutex<T>> to share mutable state across threads and channels for message passing. These primitives prevent data races at compile time, ensuring high-performance concurrent execution without runtime overhead.

Rust ownership and borrowing rules enforce memory safety by allowing either one mutable reference or multiple immutable references. Applying these idioms prevents data races at compile time, eliminating the need for garbage collection.

Use traits and generics in Rust when building reusable APIs and zero-cost abstractions. They allow polymorphic behavior without runtime overhead, enabling maintainable code that compiles to efficient machine-level implementations.

Model valid states in Rust using exhaustive enums and pattern matching. This technique enforces compile-time checks for all possible states, preventing invalid configurations and reducing runtime bugs by design.

Refactoring Rust code to improve safety and maintainability involves applying idiomatic patterns for ownership, error handling, and concurrency. This process updates modules to enforce compile-time correctness and reduce runtime bugs.
