Ecosystem Integration

Layer 2: Design Choices

Core Question

What's the right crate for this job, and how should it integrate?

Before adding dependencies:

• Is there a standard solution?
• What's the maintenance status?
• What's the API stability?

Integration Decision → Implementation

Thinking Prompt

Before adding a dependency:

1. Is it well-maintained?

   • Recent commits?
   • Active issue response?
   • Breaking changes frequency?

2. What's the scope?

   • Do you need the full crate or just a feature?
   • Can feature flags reduce bloat?

3. How does it integrate?

   • Trait-based or concrete types?
   • Sync or async?
   • What bounds does it require?

Trace Up ↑

To domain constraints (Layer 3):

"Which HTTP framework should I use?"
    ↑ Ask: What are the performance requirements?
    ↑ Check: domain-web (latency, throughput needs)
    ↑ Check: Team expertise (familiarity with framework)

Trace Down ↓

To implementation (Layer 1):

"Integrate external crate"
    ↓ m04-zero-cost: Trait bounds and generics
    ↓ m06-error-handling: Error type compatibility

"FFI integration"
    ↓ unsafe-checker: Safety requirements
    ↓ m12-lifecycle: Resource cleanup
