よくある思い込み

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.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• 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
