rpc-router 0.2.0

/// A simple macro to create a new RouterBuider from a list of handlers
/// and optionaly a list of resources
///
/// ## Pattern 1 - List of function handlers
/// ```
/// router_builder!(
///   create_project,
///   list_projects,
///   update_project,
///   delete_project
/// );
/// ```
/// Is equivalent to:
/// ```
/// RouterBuilder::default()
///     .append_dyn("create_project", create_project.into_box())
///     .append_dyn("list_projects", list_projects.into_box())
///     .append_dyn("update_project", update_project.into_box())
///     .append_dyn("delete_project", delete_project.into_box())
/// ```
///
/// ## Pattern 2 - List of function handlers, and resources
/// ```
/// router_builder!(
///   handlers: [get_task, create_task],         // will be turned into routes
///   resources: [ModelManager {}, AiManager {}] // common resources for all calls
/// );
/// ```
///
/// Is equivalent to:
///
/// ```
/// RouterBuilder::default()
///     .append_dyn("get_task", get_task.into_box())
///     .append_dyn("create_task", create_task.into_box())
///     .append_resource(ModelManager {})
///     .append_resource(AiManager {})
/// ```
///
/// ## Pattern 3 - Just for consistency with Pattern 2, we can have omit the resources
///
/// ```
/// router_builder!(
///   handlers: [get_task, create_task]
/// );
/// ```
