SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill addresses the complexity of managing dependencies in large applications by providing a flexible and performant Dependency Injection (DI) system that can be conditionally enabled, minimizing overhead when not in use.

Core Features & Use Cases

  • Rust-based DI Engine: A core DI container implemented in Rust for performance.
  • Feature Gate Architecture: DI functionality is opt-in via Cargo features, ensuring zero overhead when DI is not compiled.
  • Cross-Language Bindings: Integrates DI seamlessly with Python, Node.js, and Ruby language bindings.
  • Flexible Lifetimes: Supports Singleton and Per-Request dependency lifetimes.
  • Use Case: Easily manage complex object graphs and ensure consistent dependency resolution across different microservices or application modules without impacting performance for features that don't require DI.

Quick Start

Build the Rust project with the 'di' feature enabled using cargo build --features di.

FAQPage Schema
How do I implement a dependency injection container in Rust with zero overhead when not in use?

You can implement a Rust-based dependency injection container that is conditionally enabled using Cargo feature gates. This architecture ensures the DI system has zero overhead when the feature is not compiled into the application.

Can I use a Rust dependency injection container with Python, Node.js, and Ruby?

Yes, the Rust dependency injection container includes cross-language bindings for Python, Node.js, and Ruby. This allows you to integrate DI seamlessly across different application modules and microservices.

How do I manage singleton and per-request dependency lifetimes in a Rust web service?

The Rust DI container manages flexible dependency lifetimes, supporting both singleton and per-request scopes. It also performs cycle detection and supports lazy initialization for efficient resource management in web services.

What is the best way to enable dependency injection features in my Rust project?

The best way to enable dependency injection is by building your Rust project with the 'di' feature gate. You can activate the DI container by running the command `cargo build --features di` during your build process.

Does feature-gated dependency injection help with complex object graphs in microservices?

Feature-gated dependency injection helps manage complex object graphs and ensures consistent dependency resolution across microservices. It minimizes overhead by keeping DI opt-in via Cargo features when not required.

Why does the Rust dependency injection container perform cycle detection and lazy initialization?

The Rust DI container performs cycle detection to prevent circular dependency errors and uses lazy initialization for efficient resource management. These features ensure flexible and performant dependency resolution in large applications.
