Kotoba Core

Core components for the Kotoba graph processing system. Provides fundamental types, IR definitions, and common utilities used across the Kotoba ecosystem.

🏗️ Architecture

Kotoba Core provides the foundational building blocks:

Types: Common data types and error handling
IR: Intermediate Representation definitions for:
- Catalog management
- Query processing
- Rule systems
- Graph transformations
- Strategy patterns

📦 Components

Core Types (`types.rs`)

KotobaError: Unified error handling
Result<T>: Type alias for results
Common value types and utilities

IR Definitions (`ir/`)

catalog.rs: Schema and catalog management
query.rs: Query representation and optimization
rule.rs: Graph rewriting rules
patch.rs: Graph transformation patches
strategy.rs: Execution strategies

🔧 Usage

use kotoba_core::types::{KotobaError, Result};
use kotoba_core::ir::query::QueryIR;

// Error handling
fn process_query(query: &str) -> Result<QueryIR> {
    // Implementation
    Ok(QueryIR::default())
}

🤝 Integration

Kotoba Core is used by all other Kotoba crates:

kotoba-graph: Graph data structures
kotoba-execution: Query execution engine
kotoba-jsonnet: Configuration processing
kotoba-server: HTTP server components
