Memory profiling Rust code with heaptrack in 2019

I recently ran into a classic case of "our code is using way more memory than it should". So I took my first dive into memory profiling Rust code. I read several posts about this, including the following

Change frame rate (25 FPS to 23.976 FPS)

$ ffmpeg -y -i INPUT -vf "setpts=25025*PTS/24000" -r 23.976 -af atempo=24000/25025 OUTPUT

Git Tidbits

Removing files in post after changing `.gitignore`

$ git rm --cached `git ls-files -i -c --exclude-from=.gitignore`

In case of forgotten Windows Account Password

Boot into a recovery environment/installer
Open a command prompt
Execute regedit

In `regedit`

Select HKEY_LOCAL_MACHINE
On the menu bar, select File -> Load Hive
Navigate to <Windows Install Drive>:\Windows\system32\config\ and load SYSTEM
Give it a key name, such as 1234 (this way this key block will live on top)

Arduino CLI

Install the CLI using brew:

$ brew install arduino-cli

Add the following package repo and install:

$ arduino-cli config init --additional-urls https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
$ arduino-cli core update-index

	#!/bin/bash

	# Set script to exit on error
	set -e

	# Enable logging
	exec > >(tee -i /var/log/setup-script.log)
	exec 2>&1

	echo "Starting script execution..."

	nmcli con add \
	type wifi \
	con-name "eduroam"
	ifname "wlp4s0" \ # Your wifi interface
	ssid "eduroam" \
