nscfg

Nifty Simple CFG提供了一种改进的语法和宏，可以轻松管理一个包中所有的#[cfg]参数。查看功能获取完整的特性列表，如别名、属性、自动依赖标签文档等。

示例

将其转换成

#[cfg(any(doc, any(target_os = "linux", target_os = "macos", target_os = "windows")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "linux", target_os = "windows", target_os = "macos"))))]
pub mod desktop_mod;

#[cfg(any(doc, any(target_os = "linux", target_os = "macos", target_os = "windows")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "linux", target_os = "windows", target_os = "macos"))))]
pub use desktop_mod::Struct as Struct;

#[cfg(any(doc, any(target_os = "ios", target_os = "android")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "ios", target_os = "android"))))]
pub mod mobile_mod;

#[cfg(any(doc, any(target_os = "ios", target_os = "android")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "ios", target_os = "android"))))]
pub use mobile_mod::Struct1 as Struct1;

#[cfg(any(doc, any(target_os = "ios", target_os = "android")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "ios", target_os = "android"))))]
pub use mobile_mod::Struct2 as Struct2;

#[cfg(any(doc, any(target_os = "ios", target_os = "android")))]
#[cfg_attr(docsrs, doc(cfg(any(target_os = "ios", target_os = "android"))))]
pub fn mobile_only_fn() {}

这样的

target_cfg!{
    desktop => {
        pub mod desktop_mod;
        pub use desktop_mod::Struct as Struct;
    },
    mobile => {
        pub mod mobile_mod;
        pub use mobile_mod::Struct1 as Struct1;
        pub use mobile_mod::Struct2 as Struct2;
        pub fn mobile_only_fn() {}
    }
}
