SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies Elixir protocol definitions and implementations by allowing them to be colocated within the struct module, reducing boilerplate and improving discoverability.

Core Features & Use Cases

Colocated Protocol Definitions: Define protocols directly within the module that will implement them.
Simplified Implementation: Write protocol implementations alongside struct definitions.
Use Case: When defining a new data structure and its associated protocol behavior, keep both the struct and its protocol implementations together for easier management and understanding.

Quick Start

Use the protocols skill to define a new Elixir protocol named MyProtocol with a required function process/1.

FAQPage Schema

How do I colocate Elixir protocol definitions and implementations in the same module?▼

You can colocate Elixir protocol definitions and implementations within struct modules using the Protoss library. This Skill provides the syntax to define protocols and implement them directly in the module, reducing boilerplate and improving code discoverability.

What is the best way to organize Elixir protocol implementations for struct modules?▼

The best way to organize Elixir protocol implementations is to colocate them with your struct definitions. This approach keeps the data structure and its associated protocol behavior together for easier management and understanding.

Do I need the Protoss library to define Elixir protocols inside a struct module?▼

Yes, you need the Protoss library to enable in-module protocol definition and implementation syntax. It provides the necessary functionality to facilitate colocated Elixir protocol definitions directly within your struct modules.

Can I define a new Elixir protocol and implement it in the same struct file?▼

Yes, you can define a new Elixir protocol and implement it directly within the struct module. This allows you to write protocol implementations alongside struct definitions, enhancing code organization and maintainability.

Why colocate Elixir protocol implementations with struct definitions?▼

Colocating Elixir protocol implementations with struct definitions solves the problem of boilerplate and poor discoverability. By keeping both the struct and its protocol behavior together, code management and understanding become significantly easier.

Are there limitations to colocating Elixir protocols using the Protoss library?▼

The metadata does not specify technical limitations for colocating Elixir protocols with the Protoss library. It is primarily recommended for enhancing code organization and reducing boilerplate when defining new data structures and their associated protocol behaviors.
