* Make the value lifecycle inline-friendly Signed-off-by: Niels Lohmann <mail@nlohmann.me> * Compare standard containers without a thread-local depth count operator== on objects and arrays recursed through the containers' own operator== and counted the depth in a thread-local variable. Where reading a thread-local costs a call (macOS), that added about 10% to comparing documents with many small containers. For the standard containers, walk objects and arrays directly, compare scalars and strings inline, and pass the depth as an argument, falling back to compare_iteratively beyond the depth limit. Other container types keep the previous path. Signed-off-by: Niels Lohmann <mail@nlohmann.me> * Address review: owns_memory() helper, leaf compare naming, astyle - Add detail::owns_memory(value_t), a switch listing every enumerator so -Wswitch-enum flags it when a type is added; destroy() and the copy constructor use it instead of hand-written comparisons. Clang emits the same bitmask test as before. - Drop the parentheses around the scalar operands in JSON_IMPLEMENT_SCALAR_CASES; they are only needed for the container operands (#1530), which the comment now says. - Build equal_bounded_containers from detail::conjunction so astyle no longer pads the template brackets. - Rename equal_scalar() to equal_leaf() and document why it also compares strings, unlike JSON_IMPLEMENT_SCALAR_FAST.
