§tool-useful
A high-performance, type-safe function calling and tool orchestration framework for Rust AI applications.
§Performance Features
- ⚡ Parallel execution with configurable concurrency
- 🔄 Advanced retry policies with exponential backoff & jitter
- ⏱️ Circuit breakers to prevent cascading failures
- 📊 Built-in metrics and tracing
- 🚀 Zero-cost abstractions
§Security Features
- 🔒 Permission system (network, filesystem)
- 📏 Resource limits (memory, CPU time)
- 🛡️ Rate limiting
- 🔐 Sandboxing support
§Advanced Features
- 📡 Streaming tool execution
- 📦 Batch processing
- 🌐 Multi-provider schema export (OpenAI, Anthropic, Gemini)
