structure/zset.go:1024–1037

RemoveNode is a method for FZSet structure. This method aims to delete a node from both the dictionary (dict) and the skip list (skipList). The method receives one parameter: - member: a string that represents the key of the node to be removed from the FZSet structure. The method follows these ste

// The RemoveNode's primary purpose is to provide a way to securely and
// efficiently remove a node from the FZSet structure.
func (fzs *FZSet) RemoveNode(member string) error {
	// Check for existence of key in dictionary
	v, ok := fzs.dict[member]
	if !ok || fzs.dict == nil {

	// Delete Node from the skip list and dictionary
	fzs.skipList.delete(v.score, member)
	delete(fzs.dict, member)
	fzs.size--

	return nil
}
