func IsIndexOutOfBoundsError

func IsIndexOutOfBoundsError(err error) bool

IsIndexOutOfBoundsError returns true if input error is type of "IndexOutOfBounds".

Types

type Tuple

type Tuple interface {
	// First returns the first element in the Tuple.
	First() (reactor.Any, error)
	// Second returns the second element in the Tuple.
	Second() (reactor.Any, error)
	// Last returns the last element in the Tuple.
	Last() (reactor.Any, error)
	// Get returns the element in the Tuple with given index.
	Get(index int) (reactor.Any, error)
	// GetValue returns value of the element in the Tuple with given index.
	GetValue(index int) reactor.Any
	// Len returns the length of Tuple.
	Len() int
	// HasError returns true if Tuple contains error.
	HasError() bool
	// ForEach execute callback for each element in the Tuple.
	// If ok returns false, current loop will be broken.
	ForEach(callback func(v reactor.Any, e error) (ok bool))
	// ForEachWithIndex execute callback for each element and index in the Tuple.
	// If ok returns false, current loop will be broken.
	ForEachWithIndex(callback func(v reactor.Any, e error, index int) (ok bool))
	// CollectSlice collects values to slice.
	CollectSlice(slicePtr interface{}) error
}

Tuple is a container of multi elements.

func NewTuple

func NewTuple(items ...*reactor.Item) Tuple

NewTuple returns a new Tuple.
