initialPrefabs - No Alloc Collections Documentation

No Alloc Collections Documentation

No Alloc Collections is a library that provides stack only data structures in C#. This means that you cannot store these collections as member variables in structs or classes and can only live in the closure they are declared.

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

All data structures must be backed by your custom allocated memory. This can be done through the stackalloc keyword or aliased as a span from a managed Array.

Installation

For use within Unity please use OpenUpm.
For use with regular dotnet projects
- You can embed the source directly into your project
- Grab it on nuget

dotnet add package NoAllocCollections
