Core Concepts

Fundamental Principles

This section explains the core concepts and design principles behind the Nerve Framework.

Reactive Programming

The Nerve Framework is built on reactive programming principles:

  • Event-Driven Architecture - Components react to events and state changes
  • Data Flow - Information flows through the system via messages
  • Asynchronous Processing - Non-blocking operations for high performance

Quality of Service (QoS)

The framework provides four QoS levels:

  1. BestEffort - Messages may be dropped under load
  2. Reliable - Oldest messages dropped when buffers are full
  3. Guaranteed - Error returned when buffers are full
  4. RealTime - Latest messages prioritized, oldest overwritten

Memory Management

  • Buffer Management - Configurable message buffers with QoS policies
  • Zero-Copy Operations - Efficient message passing without data copying
  • Memory Safety - Rust's ownership model prevents common memory errors

Communication Patterns

  • Publisher/Subscriber - Decoupled message distribution
  • Request/Response - Synchronous communication patterns
  • Broadcast - One-to-many message distribution

System Architecture

  • Modular Design - Pluggable components for extensibility
  • Thread Safety - Lock-free data structures and atomic operations
  • Observability - Comprehensive monitoring and metrics collection
