在Rust编程语言中,过程宏(proc-macro)是一种强大的元编程工具,允许开发者在编译时执行自定义的代码生成任务。这些宏可以扩展Rust的语法,使得开发者能够以更简洁、更直观的方式编写代码。然而,由于过程宏的复杂性,它们的使用和学习曲线都相对陡峭。为了解决这个问题,Proc Macro Workshop项目应运而生,它提供了一系列精...

There is no macro language "%where" provided by SAS (I won't say that someone hasn't written a macro function with that name) so is a possible source of confusion for those that haven't become familiar enough with SAS. 0 Likes Reply current_thing Obsidian | Level 7 Re: proc and...

macro should work for any sort of compile-time loop; there is nothing specific to emitting enum variants. A different caller might use it for generating an expression like tuple.0 + tuple.1 + ... + tuple.511.use seq::seq; seq!(N in 0..512 { #[derive(Copy, Clone, PartialEq, Debu...
