SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Monadic patterns in Go provide explicit handling for absence, errors, and multiple outcomes, reducing boilerplate and improving type safety.

Core Features & Use Cases

Option for nullable data with explicit presence/absence, enabling safer JSON and DB modeling.
Result and Either abstractions to model errors and alternative data flows, with Do notation and pattern matching.
Pipeline sub-packages (option, result, either) for type-changing transformations, enabling readable multi-step pipelines.
Interoperability with standard library calls via TupleToResult, Try, Map, and FlatMap.

Quick Start

Convert a Go function’s (value, error) result with TupleToResult and then apply a simple Map transformation to demonstrate chainable error handling.

FAQPage Schema

How do I handle nullable data safely in Go without nil pointer panics?▼

Use the Option monad to model nullable data with explicit presence or absence in Go. This replaces nil checks with safe functional operations, improving type safety for JSON and database modeling.

How do I chain error handling operations in Go without nested if statements?▼

Convert standard function returns using TupleToResult, then apply Map and FlatMap pipelines to chain operations in Go. This enables readable, multi-step data flows that automatically propagate errors without boilerplate.

What is the best way to model multiple outcomes or error conditions in Go?▼

Use the Result and Either monads to model errors and alternative data flows in Go. These abstractions support Do notation and pattern matching for explicit, type-safe branching logic.

Does the samber/mo library require Go generics to build functional pipelines?▼

Yes, building monadic pipelines with samber/mo requires Go 1.18 or later for generics support. This ensures type-changing transformations across option, result, and either sub-packages remain fully type-safe.

How do I convert a standard Go function returning value and error into a monadic pipeline?▼

Wrap the function call with TupleToResult to convert the value and error pair into a Result monad. You can then use functional transformations like Map and FlatMap to integrate standard library calls into robust data flows.
