Module std.experimental.allocator.building_blocks.bitmapped_block


BitmappedBlock BitmappedBlock implements a simple heap consisting of one contiguous area of memory organized in blocks, each of size theBlockSize. A block is a unit of allocation. A bitmap serves as bookkeeping data, more precisely one bit per block indicating whether that block is currently allocated or not.
BitmappedBlockWithInternalPointers A BitmappedBlock with additional structure for supporting resolveInternalPointer. To that end, BitmappedBlockWithInternalPointers adds a bitmap (one bit per block) that marks object starts. The bitmap itself has variable size and is allocated together with regular allocations.
