Macro doc_gen_register 

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

Generates documentation registration function for a diagnostic.

This macro creates a registration function that can be called to register a diagnostic with a DocRegistry for documentation generation.

Example

// Define diagnostic
diag! {
    E.Auth.Token.EXPIRED: {
        message: "Token expired",
        // ...
    },
}

// Generate registration code
doc_gen_register! {
    E.Auth.Token.EXPIRED => ["json", "html"]
}

// Later, use the generated function:
let mut registry = DocRegistry::new("myapp", "1.0.0");
register_e_auth_token_expired_complete_for_doc_gen(&mut registry);
