Struct SlabAllocator

Public

A tiny slab allocator.

Allocates spans of type T in power-of-two sized blocks.

Note

This allocator has no support for merging adjacent freed blocks. Therefore it is best suited for similarly sized allocations which are relatively small.

Can be used in burst jobs.

This is faster than allocating NativeArrays using the Temp allocator, and significantly faster than allocating them using the Persistent allocator.
