Functions

func BigEqual 

func BigEqual(a, b *big.Int) bool

func FakeGenesis 

func FakeGenesis(l1 rune, l2 rune, l1GenesisNumber int) rollup.Genesis

func GenerateDeposit 

func GenerateDeposit(sourceHash common.Hash, rng *rand.Rand) *types.DepositTx

Returns a DepositEvent customized on the basis of the id parameter.

func GenerateLog
