Unity.Collections cheat sheet

The collections provided by this package fall into three categories:

The collection types in Unity.Collections whose names start with Native- have safety checks for ensuring that they're properly disposed and are used in a thread-safe manner.
The collection types in Unity.Collections.LowLevel.Unsafe whose names start with Unsafe- do not have these safety checks.
The remaining collection types are not allocated and contain no pointers, so effectively their disposal and thread safety are never a concern. These types hold only small amounts of data.

Allocators

Unity.Mathematics cheat sheet

Most of the methods in Mathematics have many overloads for different combinations of types. For example, math.abs() takes vector arguments, not just scalars, e.g. math.abs(new int3(5, -7, -1)) returns new int3(5, 7, 1). This cheat sheet does not exhaustively demonstrate all of the overloads. Consult the API reference for the full list.

	The rewrite with Unity Burst support makes the execution 40 times faster by default,
