# stepper_macros [stepper_lib]: https://github.com/SamueLNoesslboeck/stepper_lib A helper crate for proc-macros used by the [stepper_lib]. ## SyncCompGroup Includes a derive proc-macro to implement `SyncCompGroup` for a struct consisting of only fields that include `SyncComp`. ```rust use stepper_lib::prelude::*; // Simple group of components that consists of multiple fields #[derive(SyncCompGroup)] // Automatically implements SyncCompGroup #[derive(StepperCompGroup)] // Automatically implements StepperCompGroup struct TestGroup { pub base : StepperCtrl, pub arm : StepperCtrl } fn main() { let test = TestGroup { base: StepperCtrl::new_sim(StepperConst::GEN), arm: StepperCtrl::new_sim(StepperConst::GEN) }; let test_ref : &dyn SyncCompGroup<2> = &test; // Usually requires multiple curve builders let path_builder : PathBuilder<2> = test.create_path_builder(); } ```
