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
