常见的想当然

orjson.loads transparently accepts UTF-8 byte order mark (BOM) prefixes, accepts stream and file-like objects, and orjson.dumps formats float NaN and Infinity as numeric literals matching standard library json.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• orjson.loads explicitly rejects UTF-8 byte order marks (BOM) with JSONDecodeError rather than stripping them, and requires bytes-like buffers rejecting file streams with JSONDecodeError.
• assert orjson.dumps strictly serializes float NaN, Infinity, and -Infinity to JSON null rather than stdlib json non-standard literal tokens
• assert orjson.loads rejects raw NaN and Infinity tokens with JSONDecodeError adhering to RFC 8259
• assert zoneinfo.ZoneInfo timezone-aware datetimes serialize with exact UTC offsets including daylight saving adjustments
• assert OPT_OMIT_MICROSECONDS strips microsecond precision from both datetime.datetime and datetime.time objects
• assert orjson.loads parses zero-copy memoryview buffer slices without intermediate allocations or copies
• assert orjson.JSONDecodeError subclasses ValueError and json.JSONDecodeError, and JSONEncodeError subclasses TypeError
