45/**
46 A typesafe replacement for DYNAMIC_ARRAY. We do our own memory management,
47 and pre-allocate space for a number of elements. The purpose is to
48 pre-allocate enough elements to cover normal use cases, thus saving
49 malloc()/free() overhead.
50 If we run out of space, we use malloc to allocate more space.
51
52 The interface is chosen to be similar to std::vector.
53 We keep the std::vector property that storage is contiguous.
54
55 We have fairly low overhead over the inline storage; typically 8 bytes
56 (e.g. Prealloced_array<TABLE *, 4> needs 40 bytes on 64-bit platforms).
57
58 @remark
59 Unlike DYNAMIC_ARRAY, elements are properly copied
60 (rather than memcpy()d) if the underlying array needs to be expanded.
61
62 @remark
63 Depending on Has_trivial_destructor, we destroy objects which are
64 removed from the array (including when the array object itself is destroyed).
65
66 @tparam Element_type The type of the elements of the container.
67 Elements must be copyable or movable.
68 @tparam Prealloc Number of elements to pre-allocate.
