Design Philosophy
Rocket:
- Developer experience focused
- Convention over configuration
- Magic through code generation
- Easy to get started with
- Opinionated framework design
Core Web:
- Production readiness focused
- Explicit configuration over convention
- No hidden magic
- Comprehensive feature set
- Modular architecture
Both frameworks offer excellent performance, but with different trade-offs:
Rocket:
- Slightly higher compile times due to code generation
- Runtime overhead is minimal
- Excellent for rapid prototyping
Core Web:
- Optimized for production workloads
- Lower runtime overhead due to explicit design
- Better suited for high-throughput applications

- High performance through async/await
- Mature ecosystem
- Steeper learning curve due to actor concepts
Core Web:
- Built on modern async/await patterns
- Modular component architecture
- Easier learning curve for newcomers
- More comprehensive feature set
Unique Advantages of Core Web
1. Multi-Protocol Support
Unlike other frameworks that focus solely on HTTP, Core Web provides:
- REST API with full CRUD operations
- GraphQL with schema and resolvers
- gRPC with Protocol Buffer service contracts
- WebSocket/SSE for real-time communication
2. Enterprise-Grade Security
Core Web includes comprehensive security features:
- Authentication: JWT, OIDC, and API key support
- Authorization: RBAC and ABAC with Casbin/Cedar
- Security Headers: HSTS, CSP, CORS/CSRF protection
- Compliance: Data protection regulation compliance
3. Multi-Database Integration
Core Web provides seamless integration with multiple database systems:
- MySQL - Primary transactional database
- Redis - Caching, session storage, and pub/sub messaging
- MongoDB - Document storage for flexible schemas
- ClickHouse - Analytics and time-series data warehouse
4. Advanced Observability
Core Web implements comprehensive observability:
- Distributed Tracing with OpenTelemetry
- Metrics Collection and dashboarding
- Structured Logging with multiple output formats
- Health Checks with Kubernetes-ready endpoints
5. Resilience Patterns
Core Web includes proven resilience patterns:
- Retry Mechanisms with exponential backoff
- Circuit Breaker for fault tolerance
- Bulkhead for resource isolation
- Timeout for preventing resource exhaustion
Core Web is optimized for high performance:
- Caching Layers: In-memory (Moka) and Redis distributed caching
- Connection Pooling: Efficient database connection management
- Async/Await: Non-blocking I/O for maximum throughput
- Resource Management: Memory-efficient data structures

Migration from Other Frameworks
From Axum
Migration from Axum is straightforward since Core Web is built on Axum:
- Existing Axum handlers can often be used directly
- Middleware may need adaptation to Tower-based system
- Benefit from added security and observability features
From Rocket
Migration requires more changes due to different design philosophies:
- Replace Rocket guards with Axum extractors
- Adapt routing from attribute-based to macro-based
- Reimplement authentication/authorization systems
From Actix Web
Migration involves significant changes:
- Replace actor patterns with async/await
- Adapt middleware to Tower-based system
- Reimplement routing and request handling
While specific benchmarks depend on implementation details, Core Web’s performance characteristics include:
HTTP Throughput
- Comparable to Axum and Actix Web for HTTP requests
- Slight overhead from additional middleware (security, observability)
- Optimized for real-world production scenarios
Memory Usage
- Efficient memory management through Rust’s ownership system
- Configurable caching strategies
- Resource pooling for database connections
Concurrency
- Excellent async/await support
- Thread-safe operations
- Scalable to thousands of concurrent connections
