Detailed Description

template<class T>
class PLMD::Tools::FastStringUnorderedMap< T >

Tiny class implementing faster std::string_view access to an unordered_map It exposes a limited number of methods of std::unordered_map.

Others could be added. Importantly, when it is accessed via a std::string_view, the access does not require constructing a std::string and is thus faster. Deletion would be slower instead. It's not even implemented yet.
