Types

type EVM

type EVM interface {
	// Call another contract
	Call(caller vm.ContractRef, addr common.Address, data []byte, quota uint64, value *big.Int) ([]byte, uint64, error)
	// Take another's contract code and execute within our own context
	CallCode(caller vm.ContractRef, addr common.Address, data []byte, quota uint64, value *big.Int) ([]byte, uint64, error)
	// Same as CallCode except sender and value is propagated from parent to child scope
	DelegateCall(caller vm.ContractRef, addr common.Address, data []byte, quota uint64) ([]byte, uint64, error)
	// Create a new contract
	Create(caller vm.ContractRef, data []byte, quota uint64, value *big.Int) ([]byte, common.Address, uint64, error)
}

EVM provides a basic interface for the EVM calling conventions. The EVM EVM depends on this context being implemented for doing subcalls and initialising new EVM contracts.
