ButlerLogRecord

class lsst.daf.butler.logging.ButlerLogRecord(*, name: str, asctime: datetime, message: str, levelno: int, levelname: str, filename: str, pathname: str, lineno: int, funcName: str | None = None, process: int, processName: str, exc_info: str | None = None, MDC: dict[str, str])

Bases: BaseModel

A model representing a logging.LogRecord.

A LogRecord always uses the current time in its record when recreated and that makes it impossible to use it as a serialization format. Instead have a local representation of a LogRecord that matches Butler needs.
