Internal inconsistency: scope for class std::hash<...> not found! #11538
Description
Describe the bug
We have code with following pattern multiple times in our code:
#pragma once
#include <functional>
namespace NyNamespace
{
struct MyClass
{
size_t value;
};
}
template <>
struct std::hash<NyNamespace::MyClass>
{
using Key = NyNamespace::MyClass;
using result_type = size_t;
inline result_type operator()(const Key& s) const
{
return std::hash<size_t>()(s.value);
}
};This leads to:
Internal inconsistency: scope for class std::hash< NyNamespace::MyClass > not found!
To Reproduce
Generate documentation with above example.
Expected behavior
No warning is raised, as extending the namespace std is not allowed, therefore no other scope is allowed.
