public struct UnsafePtrList<T> : INativeDisposable, IDisposable, IEnumerable<nint>, IEnumerable where T : unmanaged

Value	Description
Allocator	The allocator used to create the internal buffer.
m_capacity	The number of elements that can fit in the internal buffer.
m_length	The number of elements.
Ptr	The internal buffer of this list.

Constructor	Description
UnsafePtrList`1(`0**,System.Int32)	Initializes and returns an instance of UnsafePtrList.
UnsafePtrList`1(System.Int32,Unity.Collections.AllocatorManager.AllocatorHandle,Unity.Collections.NativeArrayOptions)	Initializes and returns an instance of UnsafePtrList.

Property	Description
Capacity	The number of elements that can fit in the internal buffer.
IsCreated	Whether this list has been allocated (and not yet deallocated).
IsEmpty	Whether the list is empty.
this[]	The element at an index.
Length	The number of elements.

Method	Description
Add	Adds a pointer to the end of the list.
AddNoResize	Adds a pointer to the end of this list.
AddRange	Adds elements from a buffer to this list.
AddRangeNoResize	Copies pointers from a buffer to the end of this list.
AsParallelReader	Obsolete. Use UnsafePtrList<T>.AsReadOnly instead.
AsParallelWriter	Returns a parallel writer of this list.
AsReadOnly	Returns a read only of this list.
Clear	Sets the length to 0.
Contains	Returns true if the list contains at least one occurrence of a specific pointer.
Dispose	Releases all resources (memory).
ElementAt	Returns a reference to the element at a given index.
IndexOf	Returns the index of the first occurrence of a specific pointer in the list.
InsertRangeWithBeginEnd	Shifts pointers toward the end of this list, increasing its length.
RemoveAt	Removes the pointer at an index, shifting everything above it down by one. Decrements the length by 1.
RemoveAtSwapBack	Copies the last pointer of this list to the specified index. Decrements the length by 1.
RemoveRange	Removes "N" pointers in a range, shifting everything above the range down by "N". Decrements the length by "N".
RemoveRangeSwapBack	Copies the last "N" pointer of this list to a range in this list. Decrements the length by "N".
Resize	Sets the length, expanding the capacity if necessary.
SetCapacity	Sets the capacity.
TrimExcess	Sets the capacity to match the length.

Method	Description
Create	Returns a new list of pointers.
Destroy	Destroys the list.

Struct	Description
UnsafePtrList<T>.ParallelReader	Obsolete. Use UnsafePtrList<T>.ReadOnly instead.
UnsafePtrList<T>.ParallelWriter	A parallel writer for an UnsafePtrList\<T\>.
UnsafePtrList<T>.ReadOnly	A read only for an UnsafePtrList\<T\>.
