std::locale::id(3)

🌸 NAME 🌸

okay bestie, this is the std::locale::id(3) page from the C++ Standard Libary manual 💖 buckle up, it’s short but it’s got main character energy.

std::locale::id - std::locale::id — yes bestie, that’s the whole name section, and she is serving minimalist icon realness 👑

✨ Synopsis ✨

Defined in header <locale>

class locale::id;

So the class std::locale::id is literally the implementation-specific identification of a locale facet. Each facet has a public static member named id of type std::locale::id, and each std::locale object maintains a list of facets it implements, indexed by their ids.

Facets with the same id belong to the same facet category and replace each other when added to a locale object. periodt. ✨

💅 Member functions 💅

• constructor — constructs a new id (public member function) ✨
• operator= — copy assignment operator is deleted (public member function) 💀 no cap

🧚 Example 🧚

The following example shows how to construct a minimal custom facet.

// Run this code

#include <iostream>
#include <locale>

struct myfacet : std::locale::facet
{
    myfacet(std::size_t refs = 0) : facet(refs) {}
    static ::std::locale::id id;
};

std::locale::id myfacet::id;

int main()
{
    std::locale myloc(std::locale(), new myfacet);
    std::cout << "has_facet<myfacet>(myloc) returns " << std::boolalpha
              << std::has_facet<myfacet>(myloc) << '\n';
}

🍓 Output 🍓

has_facet<myfacet>(myloc) returns true
