Setting Length on a NativeList

Hi.

I have some cases where I want to fill a native list before using it in a IJobParallellFor job.
Using it with ToDeferredJobArray works good.

What would be good setting the length of the NativeList not having to manually fill it in a job.

NativeList<T> nativeList = NativeList(10000,Allocator.TempJob);
nativeList.Length = 10000;

The memory will aready be allocated and empty. ready to be used in the parallell job.
I need this as a list and not a NativeArray as I will need to append and remove some items later.

Would it be possible to add a set length option?

There is ResizeUninitialized which set's Capacity and Length. Most of the time uninitialized is preferrable, if not you can clear it this way:

Code (CSharp):

1. UnsafeUtility.MemClear(list.GetUnsafePtr(), list.Length * UnsafeUtility.SizeOf<T>());

@Joachim_Ante: The [list.Length * UnsafeUtility.SizeOf<T>()] bit is somewhat unsafe. It would be great if the containers all had either an ElementSize property or a way to get the complete size without specifying T seperatly.
