Detailed Description

This concept defines the required interface and semantics expected of a block allocator.

The bit::memory BlockAllocator concept is used to distribute memory blocks to allocators that can use them.

BlockAllocators are also used as upstream resources for StreamingAllocators.

The size of a memory_block returned by a BlockAllocator is fixed at construction time, and is not permitted to vary.

For type A to be BlockAllocator, it must satisfy the following:

Provided

the following expressions must be well-formed with the expected side-effects:

memory_block b = a.allocate_block()

Allocates a memory_block of implementation-specific size

a.deallocate_block( b );

Deallocates the specified block

std::size_t s = a.next_block_size()

s contains the size of the next block to be allocated
