func (Elastic[T]) Clone ¶

func (e Elastic[T]) Clone() Elastic[T]

Clone implements option.Cloner[Elastic[T]].

Clone clones its internal option.Option slice by copy. Or if T implements Cloner[T], each element is cloned.

func (Elastic[T]) Equal ¶

func (e Elastic[T]) Equal(other Elastic[T]) bool

Equal implements option.Equality[Elastic[T]].

Equal panics if T is uncomparable.

func (Elastic[T]) IsDefined ¶

func (e Elastic[T]) IsDefined() bool

IsDefined returns true if e is a defined Elastic[T], which includes a slice with no element.

func (Elastic[T]) IsNull ¶

func (e Elastic[T]) IsNull() bool

IsNull returns true if e is a null Elastic[T].

func (Elastic[T]) IsUndefined ¶

func (e Elastic[T]) IsUndefined() bool

IsUndefined returns true if e is an undefined Elastic[T].

func (Elastic[T]) IsZero ¶

func (e Elastic[T]) IsZero() bool

IsZero is an alias for IsUndefined.

func (Elastic[T]) LogValue ¶

func (e Elastic[T]) LogValue() slog.Value

LogValue implements slog.LogValuer.

func (Elastic[T]) Map ¶

func (e Elastic[T]) Map(f func(sliceund.Und[option.Options[T]]) sliceund.Und[option.Options[T]]) Elastic[T]

Map returns a new Elastic[T] whose internal value is e's mapped by f.

The internal slice of e is capped to its length before passed to f.

func (Elastic[T]) MarshalJSON ¶

func (u Elastic[T]) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler.

func (Elastic[T]) MarshalJSONV2 ¶

func (e Elastic[T]) MarshalJSONV2(enc *jsontext.Encoder, opts jsonv2.Options) error

MarshalJSONV2 implements jsonv2.MarshalerV2.

func (Elastic[T]) MarshalXML ¶

func (e Elastic[T]) MarshalXML(enc *xml.Encoder, start xml.StartElement) error

MarshalXML implements xml.Marshaler.

func (Elastic[T]) Pointer ¶

func (e Elastic[T]) Pointer() *T

Pointer returns a first value of its internal option slice as *T if e is defined.

Pointer returns nil if

• e is not defined
• e has no element
• e's first element is None.

func (Elastic[T]) Pointers ¶

func (e Elastic[T]) Pointers() []*T

Pointer returns its internal option slice as []*T if e is defined.

func (*Elastic[T]) UnmarshalJSON ¶

func (e *Elastic[T]) UnmarshalJSON(data []byte) error

UnmarshalJSON implements json.Unmarshaler.

func (*Elastic[T]) UnmarshalXML ¶

func (e *Elastic[T]) UnmarshalXML(d *xml.Decoder, start xml.StartElement) error

UnmarshalXML implements xml.Unmarshaler.

func (Elastic[T]) Unwrap ¶

func (e Elastic[T]) Unwrap() sliceund.Und[option.Options[T]]

Unwrap unwraps e.

func (Elastic[T]) Value ¶

func (e Elastic[T]) Value() T

Value returns a first value of its internal option slice if e is defined. Otherwise it returns zero value for T.

func (Elastic[T]) Values ¶

func (e Elastic[T]) Values() []T

Values returns internal option slice as plain []T.

If e is not defined, it returns nil. Any None value in its internal option slice will be converted to zero value of T.
