Detailed Description

A container that maps keys to values.

Mapping containers provide key-value pair storage with indexed access.

Example usage:

template<MappingContainer C>
auto get_or_default(C& container, typename C::key_type key,
                    typename C::mapped_type default_val) {
    auto it = container.find(key);
    return it != container.end() ? it->second : default_val;
}
