Functions

func AccountToAddress 

func AccountToAddress(accounts []types.Account) (addresses []common.Address, err error)

func FilterNamesFromRelayArgs 

func FilterNamesFromRelayArgs(args commontypes.RelayArgs) (filterNames []string, err error)

func IsLaterThan 

func IsLaterThan(incoming gethTypes.Log, existing gethTypes.Log) bool

func NewChainReader 

func NewChainReader(h httypes.HeadTracker) mercurytypes.ChainReader

func NewCodec 

func NewCodec(conf types.CodecConfig) (commontypes.RemoteCodec, error)

NewCodec creates a new commontypes.RemoteCodec for EVM. Note that names in the ABI are converted to Go names using abi.ToCamelCase, this is per convention in abi.MakeTopics, abi.Arguments.Pack etc. This allows names on-chain to be in go convention when generated. It means that if you need to use a codec.Modifier to reference a field you need to use the Go name instead of the name on-chain. eg: rename FooBar -> Bar, not foo_bar_ to Bar if the name on-chain is foo_bar_

LatestRoundRequested returns the configDigest, epoch, and round from the latest RoundRequested event emitted by the contract. LatestRoundRequested may or may not return a result if the latest such event was emitted in a block b such that b.timestamp < tip.timestamp - lookback.

If no event is found, LatestRoundRequested should return zero values, not an error. An error should only be returned if an actual error occurred during execution, e.g. because there was an error querying the blockchain or the database.

As an optimization, this function may also return zero values, if no RoundRequested event has been emitted after the latest NewTransmission event.
