template <typename NodeType, typename Allocator>class Allocations
Defined at line 64 of file ../../zircon/kernel/lib/btree/include/lib/btree_util.h
Helper object for gathering all the allocations needed to perform an insert. Internally places
the allocations in an intrusively linked list until needed. Allocations must be registered, via
reserve, in the same order (i.e. size_bytes) that they are then retrieved with take_next.

bool reserve (size_t size_bytes)Register another allocation. This will attempt the allocation and return false if it failed.
The allocation is added to the internal list.

template <typename... Args>
NodeType * take_next (size_t size_bytes, Args &&... args)Retrieves the next allocation in order. It is an error to call this if a matching reserve was
not already performed.
