Here is a quick reference of the most useful classes, interfaces, structs, and attributes that have been introduced in this documentation by ECS, the C# Job System, and the Burst compiler.
Note: This is not an exhaustive list and can be added to over time as the Unity Data-Oriented Tech Stack, and its related documentation, expands. Check the repository code and the Scripting API under the namespaces mentioned below for more examples. Be aware that links can break as the code evolves, so if you notice a problem let us know in the forums or as an issue in the repository.
