Macro export_app 

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

Export a vespera app as a reusable component.

Generates a struct with:

• OPENAPI_SPEC: &'static str - The OpenAPI JSON spec
• router() -> Router - Function returning the Axum router

Example

// Simple - uses "routes" folder by default
vespera::export_app!(MyApp);

// Custom directory
vespera::export_app!(MyApp, dir = "api");

// Generates:
// pub struct MyApp;
// impl MyApp {
//     pub const OPENAPI_SPEC: &'static str = "...";
//     pub fn router() -> axum::Router { ... }
// }
