SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps Go engineers model absence, errors, and alternative outcomes with samber/mo instead of scattered nil checks and repetitive error handling.

Core Features & Use Cases

Option for nullable values, JSON fields, and SQL columns when absence matters.
Result for chaining fallible read, parse, and validate pipelines while keeping error flow explicit.
Either and advanced monads for valid alternatives, lazy async work, and threaded state computations.
Use cases include clean database models, safer API responses, functional pipelines, and imperative monadic blocks with mo.Do.

Quick Start

Ask the assistant to refactor your Go code to use samber/mo for nullable fields, Result pipelines, and the right conversion helpers.

FAQPage Schema

How do I handle nullable values and errors in Go without scattered nil checks?▼

Functional programming in Go uses samber/mo to apply monads like Option, Result, and Either for managing absence and errors. These monads let you chain fallible read, parse, and validate operations while keeping error flow explicit and avoiding deeply nested conditionals.

What is the best way to chain fallible database row parsing in Go pipelines?▼

You refactor Go code to use samber/mo by replacing nullable struct fields with Option and wrapping fallible operations in Result pipelines. This simplifies safe composition for JSON APIs and database models by using the right conversion helpers and native serialization behavior.

Does samber/mo work for async tasks and stateful computations in Go?▼

Yes, samber/mo works for async tasks and stateful computations in Go by providing advanced monads and imperative monadic blocks via mo.Do. These features support lazy async work, valid alternatives with Either, and threaded state computations for complex functional workflows.

When should I use Either instead of Result for Go API responses?▼

A limitation of functional pipelines in Go is that overusing monads like Option and Either for simple synchronous logic can reduce readability. You should avoid forcing functional pipelines when native error handling and standard conditionals provide clearer, more idiomatic code paths.

Can I use functional programming monads for JSON API responses in Go?▼

Yes, you can use functional programming monads for JSON API responses in Go through samber/mo Option and Result. They provide native serialization behavior to safely model nullable JSON fields and fallible API responses without scattered nil checks or manual error unwrapping.
