This is a bit fragile and hacky to setup at the moment. Two things should happen to improve this configuration process
This guide is derived from the official Noetic setup page, which can be found here: http://wiki.ros.org/noetic/Installation/Source
This version includes some customizations for missing packages on Ubuntu 18.04 which the jetson nano OS uses. I think this installation should work on most ubuntu 18.04 installations, but I can give no guarantees.

Learning Rust
The following is a list of resources for learning Rust as well as tips and tricks for learning the language faster.
Warning
Rust is not C or C++ so the way your accustomed to do things in those languages might not work in Rust. The best way to learn Rust is to embrace its best practices and see where that takes you.
The generally recommended path is to start by reading the books, and doing small coding exercises until the rules around borrow checking become intuitive. Once this happens, then you can expand to more real world projects. If you find yourself struggling hard with the borrow checker, seek help. It very well could be that you're trying to solve your problem in a way that goes against how Rust wants you to work.

| Example code for displaying (and finding FPS of) gstreamer video in OpenCV. | |
| Created by Peter Moran on 7/29/17. | |
| Usage | |
| ------- | |
| After compiling, run this program with the following arguments. All are optional, but must be used cumulatively. | |
| `./gstreamer_test <width> <height> <fps> <window_size> <display_video>` | |
| For example, to display 1080p video at 30 fps and calculate the true fps over a 15 sample running window, run: |
