type EngineBackend 

type EngineBackend interface {
	CurrentSafeBlock() *types.Header
	CurrentFinalBlock() *types.Header
	GetBlockByHash(hash common.Hash) *types.Block
	GetBlock(hash common.Hash, number uint64) *types.Block

type L2EngineAPI 

type L2EngineAPI struct {
	// contains filtered or unexported fields
}

L2EngineAPI wraps an engine actor, and implements the RPC backend required to serve the engine API. This re-implements some of the Geth API work, but changes the API backend so we can deterministically build and control the L2 block contents to reach very specific edge cases as desired for testing.
