var InvalidValue = value{/* contains filtered or unexported fields */}
InvalidValue is a non nil value who's type is semantic.Invalid
Functions ¶
func NewObjectWithBacking ¶ added in v0.14.0
func NewObjectWithBacking(size int) *object
func NewObjectWithValues ¶
func UnexpectedKind ¶
Types ¶
type Array ¶
type Array interface { Value Get(i int) Value Set(i int, v Value) Append(v Value) Len() int Range(func(i int, v Value)) Sort(func(i, j Value) bool) }
Array represents an sequence of elements All elements must be the same type
type BinaryFuncSignature ¶
type BinaryFuncSignature struct { Operator ast.OperatorKind Left, Right semantic.Type }
type BinaryFunction ¶
func LookupBinaryFunction ¶
func LookupBinaryFunction(sig BinaryFuncSignature) (BinaryFunction, error)
LookupBinaryFunction returns an appropriate binary function that evaluates two values and returns another value. If the two types are not compatible with the given operation, this returns an error.
type Value ¶
type Value interface { Typer IsNull() bool Str() string Int() int64 UInt() uint64 Float() float64 Bool() bool Time() Time Duration() Duration Regexp() *regexp.Regexp Array() Array Object() Object Function() Function Equal(Value) bool }
func New ¶
func New(v interface{}) Value
New constructs a new Value by inferring the type from the interface. If the interface does not translate to a valid Value type, then InvalidValue is returned.
