Macro component 

component!() { /* proc-macro */ }

Define component enums with automatic ComponentId trait implementation.

WDP Naming Convention

Per WDP specification, component names SHOULD use PascalCase:

• ✅ Auth, Database, ApiGateway, TokenValidator
• ❌ AUTH, DATABASE, API_GATEWAY (non-standard)

Error codes follow the format: E.Component.Primary.SEQUENCE

• Example: E.Auth.Token.EXPIRED not E.AUTH.TOKEN.EXPIRED

Metadata Fields

Supports all metadata fields in any order:

• description - Documentation string
• introduced - Version introduced
• deprecated - Deprecation notice
• examples - Array of example error codes
• tags - Array of category tags

Examples

component! {
    Auth,                    // Simple: "Auth"
    Database {               // With metadata
        description: "Database operations",
        introduced: "1.0.0",
        tags: ["backend", "storage"],
    },
}

// Generated code implements ComponentIdDocumented trait:
let desc = Component::Database.description();  // Trait method
let tags = Component::Database.tags();
