cpp-enumerate

C++ 14 based, python like enumeration of C++ iterables, returning the index and value. Also works with custom iterables that require ADL.

Examples:

• with std::vector

std::vector<int> v{1, 2, 3, 4};
for (auto&& [idx, val] : rz::enumerate(v)) {
    // 
}

• custom iterable

struct Foo {
    int x;
    int * begin() { return &x; }
    int * end() { return &x + 1; }
};

for (auto&& [idx, val] : rz::enumerate(Foo{7})) {
    //
}
