SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go lacks built-in safe handling for nils and multi-step error flows. samber/mo provides type-safe Option, Result, and Either monads to encode absence and failure in the type system and to compose pipelines without boilerplate.

Core Features & Use Cases

Type-safe monads for nullable values, errors, and discriminated unions (Option, Result, Either) in Go.
Direct chaining with Map/FlatMap for same-type transforms and sub-package helpers (option, result, either) for type-changing steps.
Do notation to implement imperative-style monadic code, enabling multi-step pipelines with automatic error propagation.
Pipeline utilities (Pipe1..Pipe10) for readable, multi-step transformations across monads.

Quick Start

Install and start using samber/mo in a Go project by importing the library and a simple Option/Result example.

FAQPage Schema

How do I handle nil checks and error flows in Go pipelines?▼

To handle nil checks and error flows in Go pipelines, you can use type-safe Option and Result monads to encode absence and failure directly in the type system, eliminating boilerplate and enabling transformations that short-circuit on failure.

What is the best way to chain transformations in Go that short-circuit on failure?▼

The best way to chain transformations in Go that short-circuit on failure is applying monadic abstractions with Map and FlatMap functions, which allow multi-step data processing pipelines to automatically propagate errors without manual checks.

How do I implement imperative-style monadic code for multi-step pipelines in Go?▼

To implement imperative-style monadic code for multi-step pipelines in Go, utilize Do notation and Pipeline utilities like Pipe1 through Pipe10, enabling readable, chained transformations across Option and Result monads with automatic error propagation.

Does the samber/mo Go module support type-changing steps in functional programming?▼

Yes, the samber/mo Go module supports type-changing steps in functional programming through its sub-package helpers for Option, Result, and Either, allowing developers to safely transform values between different types within monadic pipelines.

Do I need Go 1.18 or later to use Option and Result monads?▼

Yes, you need Go 1.18 or later to use these Option and Result monads because the type-safe abstractions rely on Go's native generics support introduced in version 1.18 to encode absence and failure in the type system.

When should I use Either monads instead of Result for error handling in Go?▼

You should use Either monads instead of Result for error handling in Go when you need discriminated unions for success and failure states, whereas Result is specifically tailored for standard error handling and absence encoding.
