// FromSlogHandler returns a Logger which writes to the slog.Handler.

// ToSlogHandler returns a slog.Handler which writes to the same sink as the Logger.
//
// The returned logger writes all records with level >= slog.LevelError as
// error log entries with LogSink.Error, regardless of the verbosity level of
// the Logger:
//
//	logger := <some Logger with 0 as verbosity level>
//	slog.New(ToSlogHandler(logger.V(10))).Error(...) -> logSink.Error(...)
//
// The level of all other records gets reduced by the verbosity
// level of the Logger and the result is negated. If it happens
// to be negative, then it gets replaced by zero because a LogSink
// is not expected to handled negative levels:
//
//	slog.New(ToSlogHandler(logger)).Debug(...) -> logger.GetSink().Info(level=4, ...)
//	slog.New(ToSlogHandler(logger)).Warning(...) -> logger.GetSink().Info(level=0, ...)
//	slog.New(ToSlogHandler(logger)).Info(...) -> logger.GetSink().Info(level=0, ...)
//	slog.New(ToSlogHandler(logger.V(4))).Info(...) -> logger.GetSink().Info(level=4, ...)
