Types

type Label

type Label struct {
	Arity          int
	EndPC          uint64
	ContinuationPC uint64
}

Label acts as a signal on the workflow of the control instr

type Stack

type Stack[T any] struct {
	Values []T
	Ptr    int
}

func NewLabelStack

func NewLabelStack() *Stack[*Label]

NewLabelStack creates a new LabelStack

func NewOperandStack

func NewOperandStack() *Stack[uint64]

NewOperandStack creates a new OperandStack with no limit

func (*Stack[T]) Drop

func (s *Stack[T]) Drop()

Drop is same to Pop but no return

func (*Stack[T]) Peek

func (s *Stack[T]) Peek() T

Peek will return the value on current Ptr like Pop but Ptr does not get backspace

func (*Stack[T]) Pop

func (s *Stack[T]) Pop() T

Pop will return the value on current Ptr, and backspace the Ptr

func (*Stack[T]) Push

func (s *Stack[T]) Push(val T)
