A flat_map is a kind of associative container that supports unique keys (contains at //! most one of each key value) and provides for fast retrieval of values of another //! type T based on the keys. //! //! A flat_map satisfies all of the requirements of a container, a reversible //! container and an associative container. A flat_map also provides //! most operations described for unique keys. For a //! flat_map<Key,T> the key_type is Key and the value_type is std::pair<Key,T> //! (unlike std::map<Key, T> which value_type is std::pair<<b>const</b> Key, T>). //! //! flat_map is similar to std::map but it's implemented by as an ordered sequence container. //! The underlying sequence container is by default <i>vector</i> but it can also work //! user-provided vector-like SequenceContainers (like <i>static_vector</i> or <i>small_vector</i>). //! //! Using vector-like sequence containers means that inserting a new element into a flat_map might invalidate //! previous iterators and references (unless that sequence container is <i>stable_vector</i> or a similar //! container that offers stable pointers and references). Similarly, erasing an element might invalidate //! iterators and references pointing to elements that come after (their keys are bigger) the erased element. //! //! This container provides random-access iterators. //! //! \tparam Key is the key_type of the map //! \tparam Value is the <code>mapped_type</code> //! \tparam Compare is the ordering function for Keys (e.g. <i>std::less<Key></i>). //! \tparam AllocatorOrContainer is either: //! - The allocator to allocate <code>value_type</code>s (e.g. <i>allocator< std::pair<Key, T> > </i>). //! (in this case <i>sequence_type</i> will be vector<value_type, AllocatorOrContainer>) //! - The SequenceContainer to be used as the underlying <i>sequence_type</i>.
