func NewAllocator 

func NewAllocator(mem Memory, ptrOffset uint32) *FreeingBumpHeapAllocator

NewAllocator Creates a new allocation heap which follows a freeing-bump strategy. The maximum size which can be allocated at once is 16 MiB.

Arguments

  • `mem` - A runtime.Memory to the available memory which is used as the heap.
  • `ptrOffset` - The pointers returned by `Allocate()` start from this offset on. The pointer offset needs to be aligned to a multiple of 8, hence a padding might be added to align `ptrOffset` properly.

* returns a pointer to an initilized FreeingBumpHeapAllocator
