Cross-Language Error Handling

What problem does it solve?

This Skill addresses the complexity of managing and standardizing error reporting across different programming languages when interacting with a Rust core, ensuring consistent error payloads and predictable behavior.

Core Features & Use Cases

• Structured Error Payloads: All errors are returned as JSON with a consistent {"error": string, "code": string, "details": {}} format, regardless of the calling language.
• FFI Boundary Safety: Ensures that Rust's Result<T, E> is correctly translated into language-specific errors (e.g., Python's PyErr, Node.js's napi::Error, PHP exceptions) without exposing raw Rust error types.
• Validation Schema Alignment: Integrates with defined validation schemas to reject malformed requests early, providing clear error messages that align with the expected data structures.
• Use Case: A microservice built with Rust exposes an API used by Python, Node.js, and PHP clients. This Skill ensures that when an input validation fails or an internal Rust error occurs, all clients receive a standardized JSON error response, simplifying client-side error handling.

Quick Start

Use the cross-language error handling skill to ensure all API errors return a consistent JSON format.
