m07-concurrency
Rust concurrency design: workload classification, sharing models, and Send/Sync requirements.
- Guides decision-making between threads (CPU-bound), async (I/O-bound), and hybrid approaches before implementing
- Covers Send/Sync marker traits, thread-safety patterns (Arc, Mutex, RwLock, channels), and atomic operations with quick reference tables
- Includes mandatory "trace up" to domain skills (web, fintech, cloud-native, CLI) to align concurrency design with architectural constraints
- Highlights anti-patterns like holding MutexGuard across await, ignoring deadlock risk, and overusing Arc<Mutex> for message passing
Concurrency
Layer 1: Language Mechanics
Core Question
Is this CPU-bound or I/O-bound, and what's the sharing model?
Before choosing concurrency primitives:
- What's the workload type?
- What data needs to be shared?
- What's the thread safety requirement?
