Types ¶

type SquashSim ¶

type SquashSim struct {
	// contains filtered or unexported fields
}

SquashSim wraps an op-chain-ops MemporyStateDB, and applies EVM-messages as if they all exist in the same infinite EVM block. The result is squashing all the EVM execution changes into the state.

func NewSimulator ¶

func NewSimulator(db *state.MemoryStateDB) *SquashSim

func (*SquashSim) AddMessage ¶

func (sim *SquashSim) AddMessage(msg *core.Message) (res *core.ExecutionResult, err error)

AddMessage processes a message on top of the chain-state that is squashed into a genesis state allocation.

func (*SquashSim) AddUpgradeTxs ¶

func (sim *SquashSim) AddUpgradeTxs(txs []hexutil.Bytes) error

AddUpgradeTxs traverses a list of encoded deposit transactions. These transactions should match what would be included in the live system upgrade. The resulting state changes are squashed together, such that the final state can then be used as genesis state.

func (*SquashSim) BlockContext ¶

func (sim *SquashSim) BlockContext() *vm.BlockContext
