Struct AllocatorManager.AllocatorHandle

Represents the allocator function used within an allocator.

Namespace: Unity.Collections
Syntax
public struct AllocatorHandle : AllocatorManager.IAllocator, IDisposable

Fields

Index

This allocator's index into the global table of allocator functions.

Declaration
public ushort Index
Field Value
Type Description
UInt16

This allocator's index into the global table of allocator functions.

Version

This allocator's version number.

Declaration
public ushort Version
Field Value
Type Description

Remarks

An allocator function is uniquely identified by its combination of Index and Version together: each index has a version number that starts at 0; the version number is incremented each time the index is reused for another registered allocator function.
