Contract

• assert primitive subclasses bypass the default hook and serialize raw unless OPT_PASSTHROUGH_SUBCLASS is set
• assert dataclasses bypass the default hook and serialize all fields natively unless OPT_PASSTHROUGH_DATACLASS is set
• assert datetime objects bypass the default hook unless OPT_PASSTHROUGH_DATETIME is set
• assert OPT_UTC_Z alone has no effect on naive datetimes, requiring OPT_NAIVE_UTC composed via bitwise OR to emit Zulu format
• assert integers within 53-bit range serialize under OPT_STRICT_INTEGER while integers exceeding 2**53-1 raise TypeError
• assert orjson.Fragment splices raw buffers zero-copy and raises TypeError during dumps if the content is not bytes or str
• assert dumps parameter is singular 'option' raising TypeError on 'options', and invalid bitmasks raise TypeError
• assert OPT_APPEND_NEWLINE writes a trailing newline and composed options execute simultaneously in a single dumps pass
