Rust: can a struct hold a borrowed reference to its owner?

	struct Foo {
	bar: ~Bar
	// ^~~ error: Illegal anonymous lifetime: anonymous lifetimes are not permitted here
	}
	struct Bar<'self> {
	owner: &'self Foo
	// ^~~ error: Illegal anonymous lifetime: anonymous lifetimes are not permitted here
	}

	// Note that if Bar has _any_ borrowed reference (not just to a Foo),

Functions to replace kubernetes configmap and secret from directory

	#!/usr/bin/env bash

	# Convert a directory to a ConfigMap json file as when doing kubectl create configmap --from-file …
	#
	# Example usage:
	# 1. kubectl create cm test-cm --from-file path/to/cmdir
	#
	# 2. Before running kubectl replace, you should diff the directories:
	# dirToCm test-cm path/to/cmdir \| cmToDir /tmp/test-cm-new
	# kubectl get cm test-cm -o json \| cmToDir /tmp/test-cm-orig
