A BumpPtrAllocator that allocates slabSize at a time. slabSize initiates with initialSlabSize and doubles periodically as allocations occur. Once all memory in a slab has been used, it allocates a new slab and no memory allocations are necessary until that slab is completely filled up.
This declaration is gated by at least one @_spi attribute.
class BumpPtrAllocatorimport SwiftSyntaxA library for working with Swift code.
init(initialSlabSize: Int) Construct a new BumpPtrAllocator.
var totalByteSizeAllocated: Int { get }Total number of bytes allocated to the clients.
var totalMemorySize: Int { get }Estimated total memory size this allocator itself is consuming.
func allocate<T>(_: T.Type, count: Int) -> UnsafeMutableBufferPointer<T> Allocate a chunk of bound memory of `MemoryLayout
func allocate(byteCount: Int, alignment: Int) -> UnsafeMutableRawBufferPointer Allocate ‘byteCount’ of memory.
func contains(address: UnsafeRawPointer) -> Bool Check if the address is managed by this allocator.
