public struct NativeArray<T> : IDisposable, IEnumerable<T>, IEnumerable, IEquatable<NativeArray<T>> where T : struct

NativeArray is a fixed-size block of unmanaged memory which you can directly access from managed code. You can use NativeArray instances in jobs and Burst-compiled code, with optional safety checks for bounds, access, and dependencies. You explicitly control allocation and disposal via an allocator, and Unity tracks allocations to help detect memory leaks.
