SYSTEM DOCUMENTATION & REQUIREMENTS

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.

FAQPage Schema
How do I handle errors in domain logic without throwing exceptions?▼

Combine multiple operations without exceptions by chaining Result-returning steps using Map and Bind extension methods, which propagate failures automatically and bypass subsequent operations if an error occurs.

How do I return explicit success or failure states from a command or query?▼

Return explicit success or failure states from commands and queries by using the Result<T> factory methods, returning Result.Success(value) for valid outcomes or Result.Failure(error) for validation failures.

How do I chain multiple operations together while propagating errors?▼

Chain multiple operations without exceptions by using Map and Bind extension methods, which propagate failures automatically and bypass subsequent operations if an error occurs.

What is the Result pattern for explicit error handling?▼

Replace exceptions in your domain logic by adopting the Result pattern, which uses self-contained abstractions with factory methods and value access controls to enforce clear error semantics and predictable control flow.

When should I replace exceptions with Result types in my application?▼

Replace exceptions with Result types when you need explicit error handling across commands, queries, and services, allowing you to propagate failures with centralized Error codes and descriptive messages instead of relying on exception throwing.
