How to get parent for Node?

[evidolob]

I'm currently implementing code completion for yaml-language-server with yaml parser.
I can found AST node on which code completion was executed, but in some cases I need to get parent Node for it.
Is there any possibility to get parent node?

At least for now that's not directly available from a Node, as they do not maintain parent links. If you have a reference for the node's Document, then the easiest way to find the parent is almost certainly to visit() the doc, terminating the iteration when you find it.
