No Alloc Collections Documentation

No Alloc Collections is a library that provides stack only data structures. This means that you cannot store these collections as member variables in structs or classes.

You can store them in ref struct as they are within the closure of the stack.

Installation

For use within Unity please use OpenUpm.
For use with regular dotnet projects, please add the source in your project for now.

Planned Support

A nuget package will eventually be provided to use in dotnet projects.

NoAllocBitArray

NoAllocBitArray namespace InitialPrefabs.Collections Summary A stack only bitarray treats each bit as a boolean per byte. This means that each byte can store 8 booleans. int CalculateSize(int totalBools) Summary Calculates the total number of bytes the NoAllocBitArray can store. For example if you want to store 8 booleans, we will only need 1 byte. ...
