raz-core 0.2.4

//! # RAZ Core Library
//!
//! Universal command generator for Rust projects across multiple IDEs.
//!
//! ## Overview
//!
//! RAZ (Rust Action Zapper) provides intelligent, context-aware command generation
//! by analyzing project structure, dependencies, and cursor position to suggest
//! relevant commands for development workflows.
//!
//! ## Architecture
//!
//! - **Context Layer**: Analyzes project structure and file context
//! - **Provider Layer**: Framework-specific command generators
//! - **Filter Layer**: Rule engine for command filtering and prioritization
//! - **Command Layer**: Command execution and management
//! - **Config Layer**: Configuration management with hierarchical overrides
