TraitImpls也是一个struct,它存储了实现了某个trait的类型的相关信息。它用于查找实现了特定trait的类型,提供了一些方法来查询和操作trait实现的信息,例如根据trait和类型获取实现、根据trait获取所有实现等。 TraitSpecializationKind是一个enum,它定义了trait优化的种类。正常的trait实现是通过动态分发来实现的,但是有些特...
Struct, Union, Enum, Const, Static, Trait, TraitAlias, Impl, TypeAlias, Mod: 表示不同类型的项目,例如结构体、联合体、枚举、常量等。 MacroCall, MacroRules, MacroDef, Variant, Field: 表示宏相关的项目,例如宏调用、宏定义、宏规则等。 以下是文件中定义的trait的作用: AttrOwner: 表示具有属性的项目...

在linux内部提供的链表当中,我们可以通过container_of宏来实现从一个field指针到整个struct指针的替换,那么在C++中,我们可以用type_traits来实现这个功能。 intmain(){structpp{inta;intb; }; pp * n; remove_pointer<decltype(n)>::type m;ifconstexpr(is_same<decltype(m), pp>::value){ ...
