What is Actix Web middleware typically used for?
What is Actix Web?
What does registering a piece of middleware via `.wrap(...)` on an Actix Web `App` typically do?
Why might structuring a large Actix Web application using "scopes" (grouping related routes under a shared path prefix and middleware) be valuable?
Why might a team building a performance-critical microservice specifically choose Actix Web over a comparable framework in a garbage-collected language?
How is a basic route typically defined in Actix Web?
What is `HttpResponse` used for in an Actix Web handler function?
Why does Actix Web being built on Rust's async/await (via the Tokio runtime, among the async ecosystem) matter for its performance characteristics?
What is an "extractor" in Actix Web's handler function signatures, more generally?
What is a reasonable way to think about testing an Actix Web application, given handlers are async functions with typed extractors?
Why might error handling in Actix Web commonly use a custom error type implementing the `ResponseError` trait, rather than letting every possible error propagate identically?
