Std::hash specialisation for Identifier / unordered_map

…but the Identifier is already using the StringPool and a comparison for equality is a single operation:

WeAreROLI/JUCE/blob/master/modules/juce_core/text/juce_Identifier.h#L78


/** Creates a copy of another identifier. */

Identifier (Identifier&& other) noexcept;



/** Creates a copy of another identifier. */

Identifier& operator= (Identifier&& other) noexcept;



/** Destructor */

~Identifier() noexcept;



/** Compares two identifiers. This is a very fast operation. */

inline bool operator== (const Identifier& other) const noexcept     { return name.getCharPointer() == other.name.getCharPointer(); }



/** Compares two identifiers. This is a very fast operation. */

inline bool operator!= (const Identifier& other) const noexcept     { return name.getCharPointer() != other.name.getCharPointer(); }



/** Compares the identifier with a string. */

inline bool operator== (StringRef other) const noexcept             { return name == other; }



/** Compares the identifier with a string. */

inline bool operator!= (StringRef other) const noexcept             { return name != other; }
