func (Elastic[T]) CheckUnd ¶

func (e Elastic[T]) CheckUnd() error

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]) Elastic ¶

func (e Elastic[T]) Elastic() elastic.Elastic[T]

Elastic converts e into non-slice version Elastic[T].

The internal value of e is retained by the returned value.

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]) EqualFunc ¶

func (e Elastic[T]) EqualFunc(other Elastic[T], cmp func(i, j T) bool) bool

EqualFunc reports whether two Elastic values are equal. EqualFunc checks state of both. If both state does not match, it returns false. If both are "defined" and lengths of their internal value match, it then checks equality of their value by cmp. It returns true if they are equal.

func (Elastic[T]) HasNull ¶

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

HasNull reports e is defined value has null in ins value.

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]) Iter ¶

func (e Elastic[T]) Iter() iter.Seq[option.Option[option.Options[T]]]

Iter returns an iterator over the internal option. If e is undefined, the iterator yields nothing, otherwise the internal option.

func (Elastic[T]) Len ¶

func (e Elastic[T]) Len() int

Len returns length of values.

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]) ValidateUnd ¶

func (e Elastic[T]) ValidateUnd() error

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.
