result-pattern

What problem does it solve?

This skill introduces a disciplined approach to error handling by replacing exceptions with explicit Result and Error types, enabling predictable control flow in domain logic.

Core Features & Use Cases

• Explicit success/failure signs: Result and Result<T> carry outcomes and errors.
• Composable error handling: Use Map and Bind to chain operations without exceptions.
• Clear error semantics: Centralized Error codes and descriptive messages.

Quick Start

Create a domain operation that returns Result<T> on success or Result.Failure on error. Chain subsequent operations using Bind and Map to propagate failures. For example, implement a Create operation that validates input, then returns Result.Success(newEntity) or Result.Failure(error) and combine with other Result-returning steps.
