主要的原因是 C++ template 在 concept 和 enable_if 前是没有“类型”约束的。所以 template 在编译期的报错信息就像 python 这样的动态语言的运行期一样，需要不断带入直到展开到具体语句不匹配了才报错。而具体错误的语句，往往已经定位到函数的内部，这并不是当前程序员关心的地方。当前程序员关心的
template<typenameT> structtest{ typedefT*ptr; }; template<>// complete specialization structtest<int>{// for the case T is int T*ptr; }; 有人可能会问,为什么这是有用的,而且是真的:那看起来真的没用。但要记住,例如,std::vector的reference型看上去与其他T型完全不同。诚然,它不会将reference...

Previously, if the compiler detected that a specialization of a function template would have an abstract class type instance as a function parameter, then that specialization would be considered ill-formed. It wouldn't be added to the set of viable candidate functions. In C++20, the check for...
The library uses template specialization to customize the implementation of a given operation for specific combinations of the template parameters. The implementation uses the C7x low-level programming model, consisting of native vector (extended OpenCL) types and C7x intrinsics from . That header ...

The template options file is a user-provided optional file that contains the options needed to locate template definitions and to control instance recompilation. In addition, the options file provides features for controlling template specialization and explicit instantiation. However, because the C++ com...
