Detailed Description

template<size_t SlabSize = 4096, size_t SizeThreshold = SlabSize>
class gtirb::BumpPtrAllocatorImpl< SlabSize, SizeThreshold >

Allocate memory in an ever growing pool, as if by bump-pointer.

This isn't strictly a bump-pointer allocator as it uses backing slabs of memory rather than relying on a boundless contiguous heap. However, it has bump-pointer semantics in that it is a monotonically growing pool of memory where every allocation is found by merely allocating the next N bytes in the slab, or the next N bytes in the next slab.

Note that this also has a threshold for forcing allocations above a certain size into their own slab.
