Instead of inlining the user's function body directly into the generated trait implementation, these macros now **preserve the original user function as a standalone item** and generate trait method implementations that **call the original function by name**, injecting resources from the application context. + + This approach provides several benefits: + + - **Better debugging and error messages** — The user's function exists as a named, callable item. Stack traces, profiler output, and error messages reference the user's function name (e.g., `handle_greet`) rather than an anonymous closure or inlined block, making debugging more intuitive. + + - **Clearer macro expansion** — The generated code maintains a clear separation between the original user function and the trait glue code, reducing the cognitive load when inspecting macro-expanded output. + + _No migration is required for downstream code — the behavior of all four macros is unchanged. This is purely an internal code generation refactoring._ + #### Features: 1. **[`core`]** Added `RenderResult::new()` method for creating a new `RenderResult` with default values (empty text and exit code 0). This provides a more explicit and discoverable constructor compared to `RenderResult::default()`, making it clearer when a fresh result is being created for use with `write!`/`writeln!`. |
