如何查看由Parity Substrate中的宏生成的最终代码? [英] How can I look at the final code generated by the macros in Parity Substrate?
本文介绍了如何查看由Parity Substrate中的宏生成的最终代码?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Substrate使用许多宏来简化编写运行时模块的过程:
Substrate uses a lot of macros to make it easier to write runtime modules:
-
construct_runtime！ -
decl_module！ -
decl_storage！ -
decl_event！ - 等...
但是，很难理解这些宏的实际作用以及最终代码的外观.我该如何深入研究这些宏和扩展?
However, it is hard to understand what these macros actually do and what the final code looks like. How can I dig deeper into these macros and expansions?
推荐答案
对我来说，最舒适的解决方案是使用 cargo expand
To me, the most comfortable solution is to use cargo expand
https://github.com/dtolnay/cargo-expand
cargo install cargo-expand
然后只需从板条箱中调用它即可
then just call it from your crate
cargo expand
