Rust <--> C/C++ FFI for newbies

As Gecko is moving toward more Rust code, the cases where Rust and C code interoperate will become more common.

This document is an attempt to ease the learning curve for engineers facing it for the first time. It assumes no prior experience with cross-language C interfaces (called FFI).

It also assumes that Rust code is already built into Gecko. If you need help with that, read Introducing Rust code in Firefox.

What can you transfer across the fence

Making electron-webpack work with nodeIntegration: false

NOTE, April 18, 2020: I wrote this document in February 2019 when I was actively investigating Electron. I haven't used it since then and have largely forgotten what this was for or how electron-webpack works. I vaguely remember the problem, but that's it. It would appear based on the comments below that this document is still coming up in web searches but has become out of date and parts of it don't work. If anyone has specific fixes to my instructions, please leave them in the comments and I'll happily incorporate them.

Using electron-webpack without Node integration

Overview

The current version (as of 2019-02-02) of electron-webpack is set up with the assumption that your BrowserWindow instance has nodeIntegration: true. However, Electron is encouraging users to set nodeIntegration: false as a security precaution, and in the future BrowserWindows will have this setting set to false by default. Doing so now with electron-webpack throws an error because the index.html template has commonjs re

statement on event-stream compromise

Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.
