• Code: Error identifier (e.g., E1001)
• Category: Phase to which the error belongs
• Title: Brief description of the error
• Message: Detailed error message
• Help: Possible solutions

// Find the error code, and obtain the title and help information through I18nRegistry
let i18n = I18nRegistry::default();

if let Some(code) = ErrorCodeDefinition::find("E1001") {
    let title = i18n.get_title(&code);
    println!("Title: {}", title);

    if let Some(help) = i18n.get_help(&code) {
