ChunkGCAllocator

Namespace for a static, thread-local, non-nested, unbounded-size allocator.

Memory is allocated bump-the-pointer style within large GC-allocated chunks. A new chunk is allocated when the current one is too full for the next request. Deallocation of chunks is handled by the GC, and destructors are not called.

struct ChunkGCAllocator {

static size_t peek();

static bool inRegion();

static void enter(size_t chunkSize);

static void exit();

static void[] alloc(size_t size);

static auto alloc(Args args);

}

alloc void[] alloc(size_t size): Allocates the next size bytes from the region and returns a slice to it.
alloc auto alloc(Args args): Allocates at least T.sizeof bytes, emplaces a T there, and returns a pointer to it.
enter void enter(size_t chunkSize): Have the calling thread enter the region with a chunks of size chunkSize.
exit void exit(): Have the calling thread exit the region, releasing any references to an allocated chunk.
inRegion bool inRegion()
peek size_t peek(): Peek at the current head of the region. This value can be used to check how many bytes have been allocated so far in the current chunk.
