Types

type Context

	Caller         common.Uint168
	Code           []byte
	Input          []byte
	CodeHash       common.Uint168
	CacheCodeTable interfaces.IScriptTable
	Time           *big.Int
	BlockNumber    *big.Int
	SignableData   SignableData
	StateMachine   ns.StateMachine

}

type Engine

type Engine interface {
	Create(caller common.Uint168, code []byte) ([]byte, error)
	Call(caller common.Uint168, codeHash common.Uint168, input []byte) ([]byte, error)
}

type SignableData

type SignableData interface {
	interfaces.IDataContainer
