Cursively VS UnityCsReference

I was looking at the CSV parser Cursively recently, and I think it is a good simple example of a high performance C# parser and API design.

Agreed, and agreed. #21 and #22 seek to address this, but these have actually been very low priority for me: as your benchmarks show, if you primarily need a bunch of objects that must be UTF-16 strings, then are other libraries out there that will do the job just fine. The main reason to use Cursively for that would be if you have some use cases where you need the unusual qualities that Cursively offers, but other use cases where you can live with something more traditional, and you don't want to have two different CSV processing libraries.

The usage instructions are in the README on https://github.com/airbreather/Cursively. The most straightforward way to get started (for now) is:

I've checked their CS reference code on their Github, both here and here, but I want to dive a little deeper - specifically, I want to know what they're actually doing when determining validity of the Matrix4x4.

Yep, but beyond just decompiling it, the c# layer of code is on GitHub: https://github.com/Unity-Technologies/UnityCsReference

https://github.com/Unity-Technologies/UnityCsReference/blob/master/Runtime/Export/Scripting/UnityEngineObject.bindings.cs (after 2019.1)

The code where the method filtering for the Animation Event Inspector is done, is here (line 190). Is it possible to do something like this? That repository explicitly says:

No reason, you can look at the source of encapsulate

There isn't really a straight forward way to do this, even the QualitySettings editor uses Serialised Properties to get at the data. (Line 343 in QualitySettingsEditor)

This is awesome, thank you! I'm most curious about their Runtime

I think if you want to get into graphics programming you do want to work with OpenGL and similar things, because at the very least you need to understand it all (and decide what parts of engines to use and what to ignore when you get to whole games). It's also worth saying that while you can only publicly get the references in Unity you do get source access at the higher subscription tiers you'd use at a game studio.
