This Skill unit solves the problem of managing dependencies that require a unique instance per HTTP request in Rust applications, such as database transactions or request-specific state.
Use the injectable skill to define a request-scoped dependency in your Axum application.

Per-request dependency injection in Axum uses the `Inject<T>` extractor to instantiate services uniquely for each HTTP request. This maintains isolation for dependencies like database transactions, ensuring no state conflicts occur across concurrent web requests.
You need request-scoped dependencies when your HTTP requests require isolated state, such as unique database transactions or request-specific data. Request-scoped scoping ensures each HTTP request receives its own dedicated instance, preventing data conflicts.
You set up request-scoped services by defining dependencies with the `injectable` crate and retrieving them in Axum handlers via the `Inject<T>` extractor. This ensures a fresh instance is created and injected per HTTP request.
Yes, the injectable crate provides compile-time safety for dependency injection. It catches circular dependencies and missing service registrations during the Rust build process, preventing runtime errors commonly associated with dynamic injection frameworks.
No, this request-scoped dependency injection mechanism specifically requires the Axum web framework. It integrates tightly with Axum's `Inject<T>` extractor system to manage the lifecycle of request-scoped instances.
