-In C, a stack of unpack context is implemented as a std::vector. MSGPACK_EMBED_STACK_SIZE means the hint of the composite level. msgpack reserves MSGPACK_EMBED_STACK_SIZE elements of the std::vector. If the msgpack format byte stream contains over MSGPACK_EMBED_STACK_SIZE elements, std::vector is expanded. You can set the limit of the composite level.
