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
| Need | Choice | Crates |
|---|---|---|
| Serialization | Derive-based | serde, serde_json |
| Async runtime | tokio or async-std | tokio (most popular) |
| HTTP client | Ergonomic | reqwest |
| HTTP server | Modern | axum, actix-web |
| Database | SQL or ORM | sqlx, diesel |
| CLI parsing | Derive-based | clap |
| Error handling | App vs lib | anyhow, thiserror |
| Logging | Facade | tracing, log |
---
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)| Question | Trace To | Ask |
|---|---|---|
| Framework choice | domain-* | What constraints matter? |
| Library vs build | domain-* | What's the deployment model? |
| API design | domain-* | Who are the consumers? |
---
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---
Quick Reference
Language Interop
| Integration | Crate/Tool | Use Case |
|---|---|---|
| C/C++ → Rust | bindgen | Auto-generate bindings |
| Rust → C | cbindgen | Export C headers |
| Python ↔ Rust | pyo3 | Python extensions |
| Node.js ↔ Rust | napi-rs | Node addons |
| WebAssembly | wasm-bindgen | Browser/WASI |
Cargo Features
| Feature | Purpose |
|---|---|
[features] | Optional functionality |
default = [...] | Default features |
feature = "serde" | Conditional deps |
[workspace] | Multi-crate projects |
Error Code Reference
| Error | Cause | Fix |
|---|---|---|
| E0433 | Can't find crate | Add to Cargo.toml |
| E0603 | Private item | Check crate docs |
| Feature not enabled | Optional feature | Enable in features |
| Version conflict | Incompatible deps | cargo update or pin |
| Duplicate types | Different crate versions | Unify in workspace |
---
Crate Selection Criteria
| Criterion | Good Sign | Warning Sign |
|---|---|---|
| Maintenance | Recent commits | Years inactive |
| Community | Active issues/PRs | No response |
| Documentation | Examples, API docs | Minimal docs |
| Stability | Semantic versioning | Frequent breaking |
| Dependencies | Minimal, well-known | Heavy, obscure |
---
Anti-Patterns
| Anti-Pattern | Why Bad | Better |
|---|---|---|
extern crate | Outdated (2018+) | Just use |
#[macro_use] | Global pollution | Explicit import |
Wildcard deps * | Unpredictable | Specific versions |
| Too many deps | Supply chain risk | Evaluate necessity |
| Vendoring everything | Maintenance burden | Trust crates.io |
