Returns the maximum number of elements the allocator can provide.
- Returns:
- the maximum number of elements the allocator can provide
Internally, preprocessor macros are used rather than std::numeric_limits because the latter is not a constexpr. Some compilers, like Clang, do not optimize it well under all circumstances. Compilers like GCC, ICC and MSVC appear to optimize it well in either form.
