# std.experimental.allocator.gc_allocator

struct GCAllocator;
  D's built-in garbage-collected allocator.
  Examples:

      auto buffer = GCAllocator.instance.allocate(1024 * 1024 * 4);
      // deallocate upon scope's end (alternatively: leave it to collection)
      scope(exit) GCAllocator.instance.deallocate(buffer);
      //...

  enum uint alignment;
    The alignment is a static constant equal to platformAlignment, which ensures proper alignment for any D data type.
  shared @trusted void[] allocate(size_t bytes);
  shared @system bool expand(ref void[] b, size_t delta);
  shared @system bool reallocate(ref void[] b, size_t newSize);
  shared void[] resolveInternalPointer(void* p);
  shared @system bool deallocate(void[] b);
  shared size_t goodAllocSize(size_t n);
    Standard allocator methods per the semantics defined above. The deallocate and reallocate methods are @system because they may move memory around, leaving dangling pointers in user code.
  static shared GCAllocator instance;
    Returns the global instance of this allocator type. The garbage collected allocator is thread-safe, therefore all of its methods and instance itself are shared.
