rb_size/2Size is the number of elements in Tree.Source
rb_update/4Tree NewTree is tree Tree, but with value for Key associated with NewVal.Source
rb_update/5Same as rb_update(Tree, Key, NewVal, NewTree) but also unifies OldVal with the value associated with Key in Tree.Source
rb_visit/2Pairs is an infix visit of tree Tree, where each element of Pairs is of the form Key-Value.Source
