To use `Arc<dyn Trait>` with async functions in Rust, you wrap your trait object in an `Arc` for thread-safe reference counting, enabling dynamic dispatch and asynchronous invocation within extensible codebases. This Skill demonstrates the integration patterns and common pitfalls to avoid.

You need dynamic dispatch with trait objects in async Rust applications when building flexible architectures like plugin systems. It allows the core application to manage and invoke different modules implementing a common trait asynchronously without knowing concrete types at compile time.

Common pitfalls of managing trait objects in asynchronous Rust contexts include handling lifetimes correctly within async functions and avoiding runtime errors during dynamic dispatch. This Skill explains these potential issues and demonstrates patterns to safely integrate `Arc<dyn Trait>` with `async/await`.

Yes, using trait objects for dynamic dispatch works with `async/await` patterns by leveraging `Arc<dyn Trait>` to manage shared state across asynchronous tasks. This approach enables extensible Rust code, though it requires careful management of the trait object's lifecycle.

The best way to build an async plugin system in Rust using trait objects is defining a common trait for modules, implementing it for individual plugins, and using `Arc<dyn Trait>` to dynamically dispatch and invoke them asynchronously within the core application.
