AdditionalBytes Struct Reference

#include <allocation.h>

Public Member Functions
constexpr	AdditionalBytes (size_t bytes)

Data Fields
const size_t	value

Detailed Description

Passed to MakeGarbageCollected to specify how many bytes should be appended to the allocated object.

Example:

class InlinedArray final : public GarbageCollected<InlinedArray> {
 public:
  explicit InlinedArray(size_t bytes) : size(bytes), byte_array(this + 1) {}
  void Trace(Visitor*) const {}
 
  size_t size;
  char* byte_array;
};
 
auto* inlined_array = MakeGarbageCollected<InlinedArray(
   GetAllocationHandle(), AdditionalBytes(4), 4);
for (size_t i = 0; i < 4; i++) {
  Process(inlined_array->byte_array[i]);
}
