This class is a Boolean metafunction that determines whether or not the specified FN template parameter should be allocated within the footprint of the InplaceBuffer (i.e., using the small-object optimization.)
Declared in <bslstl_function_smallobjectoptimization.h>
template<class FN>
struct IsInplaceFunc
: bsl::integral_constant<bool, SooFuncSize<FN>::value <= sizeof(InplaceBuffer)># Implementation Note In the future, InplaceFunc should also consider the alignment of FN in its determination of whether or not bsl::function will use the small-object optimization. However, bsl::function currently has no way to specify alignment when it allocates memory.
