写web项目或者app等,必不可少的要接受参数和校验参数的准确性,基本也是项目开始的第一步,那么我们今天来看下rust提供了哪些优秀的crates
然后主目录的 build.rs 设置这些 flag 到 ""cargo:rustc-cfg" ,rustc-cfg 的作用是: Therustc-cfginstruction tells Cargo to pass the given value to theef="https://doc.rust-lang.org/rustc/command-line-arguments.html#option-cfg">--cfg flag to the compiler. This may be used for compile-...
