Method WithLazy

logger.go:202–209

WithLazy creates a child logger and adds structured context to it lazily. The fields are evaluated only if the logger is further chained with [With] or is written to with any of the log level methods. Until that occurs, the logger may retain references to objects inside the fields, and logging will

(fields ...Field)

//
// Similar to [With], fields added to the child don't affect the parent, and vice versa.
func (log *Logger) WithLazy(fields ...Field) *Logger {
	if len(fields) == 0 {
		return log
	}
	return log.WithOptions(WrapCore(func(core zapcore.Core) zapcore.Core {
		return zapcore.NewLazyWith(core, fields)
	}))
}

// Level reports the minimum enabled level for this logger.
