SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Dependency injection with traits can be complex and error-prone. This Skill simplifies the process, making it easier to create mock implementations and use trait objects in DI.

Core Features & Use Cases

  • Trait Injection: Allows traits to be injected into your application, simplifying the creation of mock implementations and the use of trait objects.
  • Axum Compatibility: Traits can be used with Axum's typed extractor model, enabling seamless integration with your web application.
  • Error Handling: Provides strong error handling and validation to catch issues early, ensuring a stable and reliable application.

Quick Start

Use the injectable-trait skill to define a new trait and create a service that implements it, then inject the service into your application container.

FAQPage Schema
How do I use dependency injection with traits in Rust?

Trait injection in Rust allows you to inject traits into your dependency injection container, simplifying the creation of mock implementations and the use of trait objects. This Skill enables that process with robust error handling.

How do I inject traits using Axum extractors?

Yes, trait injection integrates seamlessly with Axum's typed extractor model. This allows you to use injected traits directly as extractors in your web application routes, ensuring reliable dependency resolution.

Can I create mock implementations for Rust dependency injection?

Creating mock implementations is a primary use case for trait injection. By defining traits and injecting them into your application container, you can easily substitute real implementations with mocks for testing.

What is the best way to handle errors when using trait objects in Rust?

Using trait injection provides strong error handling and validation to catch dependency issues early. This ensures your Rust application remains stable and reliable when resolving trait objects.

Why is dependency injection with trait objects complex in Rust?

Dependency injection with traits can be error-prone due to Rust's strict type system and object safety rules. This Skill simplifies the process by managing trait object resolution and validation automatically.

Does injectable-trait work without a web framework?

The Skill is compatible with Axum for typed extractors but fundamentally simplifies trait injection and mock creation for general Rust applications. It provides robust error handling independent of web contexts.
