ose-error

ose-error is a structured and reusable Go error package for building microservices and APIs. It provides:

• Structured error types with codes and messages
• Error wrapping for context
• Validation errors support
• gRPC and HTTP error mapping
• Clean/sanitized errors for API clients

It’s designed to work seamlessly across microservices, keeping error handling consistent and maintainable.
