Member Function Documentation

AllocateAsync() [1/2]

MultiBufAllocationFuture pw::multibuf::MultiBufAllocatorAsync::AllocateAsync	(	size_t	min_size,
		size_t	desired_size
	)

Asynchronously allocates a MultiBuf of at least min_size bytes and at most `desired_size bytes.

Memory allocated by an arbitrary MultiBufAllocator does not provide any alignment requirements, preferring instead to allow the allocator maximum flexibility for placing regions (especially discontiguous regions).

Return values

A	MultiBufAllocationFuture which will yield a MultiBuf when one is available.

AllocateAsync() [2/2]

MultiBufAllocationFuture pw::multibuf::MultiBufAllocatorAsync::AllocateAsync

(

size_t

size

)

Asynchronously allocates a MultiBuf of exactly size bytes.

Memory allocated by an arbitrary MultiBufAllocator does not provide any alignment requirements, preferring instead to allow the allocator maximum flexibility for placing regions (especially discontiguous regions).

Return values

A	MultiBufAllocationFuture which will yield a MultiBuf when one is available.

AllocateContiguousAsync() [1/2]

MultiBufAllocationFuture pw::multibuf::MultiBufAllocatorAsync::AllocateContiguousAsync	(	size_t	min_size,
		size_t	desired_size
	)

Asynchronously allocates an OwnedChunk of at least min_size bytes and at most desired_size bytes.

Return values

A	MultiBufAllocationFuture which will yield an MultiBuf consisting of a single Chunk when one is available.

AllocateContiguousAsync() [2/2]

MultiBufAllocationFuture pw::multibuf::MultiBufAllocatorAsync::AllocateContiguousAsync

(

size_t

size

)

Asynchronously allocates a contiguous MultiBuf of exactly size bytes.

Memory allocated by an arbitrary MultiBufAllocator does not provide any alignment requirements, preferring instead to allow the allocator maximum flexibility for placing regions (especially discontiguous regions).

Return values

A	MultiBufAllocationFuture which will yield an MultiBuf consisting of a single Chunk when one is available.
