Macro bundle 

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

Collects bundle parts (routes, tasks, signals) into a Bundle for composition and registration.

Bundles are the primary unit for organizing and composing application components. Each handler must be annotated with appropriate macros (#[route], #[cron], #[periodic], etc.).

Syntax

bundle! {
    handler1,
    handler2,
    ...,
    tags = ["tag1", "tag2"]  // optional, applies only to routes
}

Options

• tags - Optional array of tags to apply to all routes in the bundle. These tags extend (not replace) any tags defined on individual routes. Note: tags only apply to route parts, not other bundle parts.

Examples

// Bundle without tags
let user_bundle = bundle! {
    get_user,        // #[route]
    create_user,     // #[route]
    sync_users,      // #[cron]
};
 
// Bundle with tags - extends individual route tags
let api_bundle = bundle! {
    tags = ["api", "v1"],
    get_user,
    create_user,
};
 
// Compose bundles
let all_bundles = bundle! {
    user_bundle,
    api_bundle,
};

Notes

• Handlers must be annotated with #[route], #[cron], #[periodic], #[pgnotify], or #[signal]
• Handlers can be free functions or references to IntoBundle types
• Tags are additive and only apply to route parts
• Returns a Bundle that implements IntoBundle
