Gateway Routing Generator

[GenerateGatewayRouting] creates a typed GatewayRouting<TRequest, TResponse> factory from route predicates, matching route handlers, and one fallback handler.

[GenerateGatewayRouting(typeof(ProductGatewayRequest), typeof(ProductGatewayResponse), GatewayName = "product-gateway-routing")]
public static partial class ProductGateway
{
    [GatewayRoute("inventory")]
    private static bool IsInventory(ProductGatewayRequest request) => request.Path.StartsWith("/inventory/");

    [GatewayRouteHandler("inventory")]
    private static ProductGatewayResponse Inventory(ProductGatewayRequest request) => new("inventory", request.Path);

    [GatewayRouteFallback("not-found")]
    private static ProductGatewayResponse NotFound(ProductGatewayRequest request) => new("fallback", request.Path);
}
