Function Reflect

field.go:326–328

Reflect constructs a field with the given key and an arbitrary object. It uses an encoding-appropriate, reflection-based function to lazily serialize nearly any object into the logging context, but it's relatively slow and allocation-heavy. Outside tests, Any is always a better choice. If encoding

(key string, val interface{})

// If encoding fails (e.g., trying to serialize a map[int]string to JSON), Reflect
// includes the error message in the final log output.
func Reflect(key string, val interface{}) Field {
	return Field{Key: key, Type: zapcore.ReflectType, Interface: val}
}

// Namespace creates a named, isolated scope within the logger's context. All
// subsequent fields will be added to the new namespace.
