type Flag struct {
	Name          string
	Type          descriptor.FieldDescriptorProto_Type
	Message       string
	Repeated      bool

}

Flag is used to represent fields as flags

func (*Flag) GenFlag

func (f *Flag) GenFlag() string

GenFlag generates the pflag API call for this flag

func (*Flag) IsBytes

func (f *Flag) IsBytes() bool

IsBytes is a helper that reports if the flag is of a type bytes

func (*Flag) IsEnum

func (f *Flag) IsEnum() bool

IsEnum is a template helper that reports if the flag is of an enum type

func (*Flag) IsMessage

func (f *Flag) IsMessage() bool

IsMessage is a template helper that reports if the flag is a message type

type NestedMessage

type NestedMessage struct {
	FieldName string
	FieldType string
}

NestedMessage represents a nested message that will need to be initialized in the generated code
