std.experimental.allocator.building_blocks.null_allocator
- struct NullAllocator;
- NullAllocator is an emphatically empty implementation of the allocator interface. Although it has no direct use, it is useful as a "terminator" in composite allocators.
- enum uint alignment;
- shared void[] allocate(size_t);
- Returns n.Always returns null.
- shared void[] alignedAllocate(size_t, uint);
- Always returns null.
- shared void[] allocateAll();
- Always returns null.
- shared bool expand(ref void[] b, size_t);
shared bool reallocate(ref void[] b, size_t);
shared bool alignedReallocate(ref void[] b, size_t, uint); - These methods return false.
Precondition: b is null. This is because there is no other possible legitimate input.
- shared const Ternary owns(void[]);
- Returns Ternary.no.
- shared const void[] resolveInternalPointer(void*);
- Returns null.
- shared bool deallocate(void[] b);
- No-op.
Precondition: b is null
- shared bool deallocateAll();
- No-op.
- shared const Ternary empty();
- Returns Ternary.yes.
- static NullAllocator instance;
