Rust Error Handling Cheatsheet - Result handling functions

Introduction to Rust error handling

Rust error handling is nice but obligatory. Which makes it sometimes plenty of code.

Functions return values of type Result that is "enumeration". In Rust enumeration means complex value that has alternatives and that alternative is shown with a tag.

Result is defined as Ok or Err. The definition is generic, and both alternatives have

	#!/usr/bin/env bash

	pod_created=false
	trap del-pod EXIT

	help()
	{
	echo "Build image using kaniko and output a tarball representing the built image.
	Tarball of built image can then be managed (show digest, push, etc.) using crane/gcrane.

	#!/usr/bin/env bash

	# get all pipenv environments
	allPipenvEnv=$(find ~/.local/share/virtualenvs/*/.project -type f)

	# find abandoned environments
	abandonedEnv=()
	for f in $allPipenvEnv; do
	proj_path="$(cat $f)" && [ ! -d $proj_path ] && abandonedEnv+=($proj_path)
	done

	docker run -v /Users/mbreese/tmp:/tmp1 -w /tmp1 -i centos:7 /bin/bash -s <<EOF
	date > foo
	echo 'foo' >> foo
	cat /etc/redhat-release >> foo
	whoami >> foo
	EOF

	#!/bin/bash
