Detailed Description

template<typename T>
struct LibXR::Detail::RuntimeStringArgumentTraits< T >

Compile-time traits for formatted retained-string arguments.

格式化保留字符串参数的编译期类型特征。

The formatted variant must allocate before seeing future values, so only bounded value-like argument types are accepted. Text-like runtime arguments are intentionally rejected and should be handled by the plain concatenation constructor instead.

格式化版本必须在看到未来值之前完成分配，因此这里只接受长度可界定的 值类型参数。运行期文本参数会被拒绝，应改用普通拼接构造。
