func NewListOpts

func NewListOpts(validator ValidatorFctType) ListOpts

NewListOpts creates a new ListOpts with the specified validator.

func NewListOptsRef

func NewListOptsRef(values *[]string, validator ValidatorFctType) *ListOpts

func NewNamedListOptsRef

func NewNamedListOptsRef(name string, values *[]string, validator ValidatorFctType) *NamedListOpts

NewNamedListOptsRef creates a reference to a new NamedListOpts struct.

func (*NamedListOpts) Name

func (o *NamedListOpts) Name() string

Name returns the name of the NamedListOpts in the configuration.

type NamedOption

type NamedOption interface {
	Name() string
}
