Types ¶
type Output ¶
type Output struct {
Data []byte
Events tx.Events
Transfers tx.Transfers
LeftOverGas uint64
RefundGas uint64
VMErr error // VMErr identify the execution result of the contract function, not evm function's err.
ContractAddress *workshare.Address // if create a new contract, or is nil.
}
Output output of clause execution.
type ResolvedTransaction ¶
type ResolvedTransaction struct {
Origin workshare.Address
Delegator *workshare.Address
IntrinsicGas uint64
Clauses []*tx.Clause
// contains filtered or unexported fields
}
ResolvedTransaction resolve the transaction according to given state.
func ResolveTransaction ¶
func ResolveTransaction(tx *tx.Transaction) (*ResolvedTransaction, error)
ResolveTransaction resolves the transaction and performs basic validation.
func (*ResolvedTransaction) BuyGas ¶
func (r *ResolvedTransaction) BuyGas(state *state.State, blockTime uint64) ( baseGasPrice *big.Int, gasPrice *big.Int, payer workshare.Address, returnGas func(uint64) error, err error, )
BuyGas consumes energy to buy gas, to prepare for execution.
func (*ResolvedTransaction) CommonTo ¶
func (r *ResolvedTransaction) CommonTo() *workshare.Address
CommonTo returns common 'To' field of clauses if any. Nil returned if no common 'To'.
type Runtime ¶
type Runtime struct {
// contains filtered or unexported fields
}
Runtime bases on EVM and VeChain Thor builtins.
func New ¶
func New( chain *chain.Chain, state *state.State, ctx *xenv.BlockContext, forkConfig workshare.ForkConfig, ) *Runtime
New create a Runtime object.
func (*Runtime) Context ¶
func (rt *Runtime) Context() *xenv.BlockContext
func (*Runtime) ExecuteTransaction ¶
ExecuteTransaction executes a transaction. If some clause failed, receipt.Outputs will be nil and vmOutputs may shorter than clause count.
func (*Runtime) PrepareClause ¶
func (rt *Runtime) PrepareClause( clause *tx.Clause, clauseIndex uint32, gas uint64, txCtx *xenv.TransactionContext, ) (exec func() (output *Output, interrupted bool, err error), interrupt func())
PrepareClause prepare to execute clause. It allows to interrupt execution.
func (*Runtime) PrepareTransaction ¶
func (rt *Runtime) PrepareTransaction(tx *tx.Transaction) (*TransactionExecutor, error)
PrepareTransaction prepare to execute tx.
func (*Runtime) SetVMConfig ¶
SetVMConfig config VM. Returns this runtime.
