(I plan to publish this as a blog post once a few people have looked at it and caught the obvious typos.)

I got lots of positive feedback about the FAQ section in my Rust 2020 blog post, so I'm trying that format again for another topic that's been requested a lot: How to fix common borrow-checker issues. This isn't meant to explain how or why the borrow checker works the way it does (see The Nomicon or Two Beautiful Rust Programs for that), just how to work around some of its current limitations.

DuckInterface

I was playing with new .Net 5 and the Source Generator lately and got an idea that it is possible to add "duck typing" support to C#. I would say it is purely academic(no one will use it in production I hope), but it is fun stuff so I decided to try.

The nuget package with results you can find here

The repository is here: https://github.com/byme8/DuckInterface

	/**
	* I needed a property wrapper that fulfilled the following four requirements:
	*
	* 1. Values are stored in UserDefaults.
	* 2. Properties using the property wrapper can be used with SwiftUI.
	* 3. The property wrapper exposes a Publisher to be used with Combine.
	* 4. The publisher is only called when the value is updated and not
	* when_any_ value stored in UserDefaults is updated.
	*
	* First I tried using SwiftUI's builtin @AppStorage property wrapper
