github.com/lorenzosaino/go-orderedmap (go): Package orderedmap implements an ordered map using generics.  An ordered map is a map whose values are ordered and all connected with a doubly-linked list. It provides O(1) lookup, update, removal, insertion to front/back, insertion before/after a specific key, move to front/back, move before/after a specific key.  This implementation is not safe for concurrent usage. You may want to use a sync.RWLock to synchronize access to it if you intend to use it concurrently.
