Types

type ArbitrumBlockTranslator 

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

ArbitrumBlockTranslator uses Arbitrum's special L1BlockNumber to optimise log lookups Performance matters here hence aggressive use of the cache We want to minimise fetches because calling eth_getBlockByNumber is relatively expensive

func NewArbitrumBlockTranslator 

func NewArbitrumBlockTranslator(ethClient evmclient.Client, lggr logger.Logger) *ArbitrumBlockTranslator

NewArbitrumBlockTranslator returns a concrete ArbitrumBlockTranslator

func (*ArbitrumBlockTranslator) BinarySearch 

func (a *ArbitrumBlockTranslator) BinarySearch(ctx context.Context, targetL1 int64) (l2lowerBound *big.Int, l2upperBound *big.Int, err error)

BinarySearch uses both cache and RPC calls to find the smallest possible range of L2 block numbers that encompasses the given L1 block number

Imagine as a virtual array of L1 block numbers indexed by L2 block numbers L1 values are likely duplicated so it looks something like [42, 42, 42, 42, 42, 155, 155, 155, 430, 430, 430, 430, 430, ...] Theoretical max difference between L1 values is typically about 5, "worst case" is 6545 but can be arbitrarily high if sequencer is broken The returned range of L2s from leftmost thru rightmost represent all possible L2s that correspond to the L1 value we are looking for nil can be returned as a rightmost value if the range has no upper bound

func (*ArbitrumBlockTranslator) NumberToQueryRange 

func (a *ArbitrumBlockTranslator) NumberToQueryRange(ctx context.Context, changedInL1Block uint64) (fromBlock *big.Int, toBlock *big.Int)

NumberToQueryRange implements BlockTranslator interface

type BlockTranslator 

type BlockTranslator interface {
	NumberToQueryRange(ctx context.Context, changedInL1Block uint64) (fromBlock *big.Int, toBlock *big.Int)
}

BlockTranslator converts emitted block numbers (from block.number) into a block number range suitable for query in FilterLogs

func NewBlockTranslator(cfg Config, client evmclient.Client, lggr logger.Logger) BlockTranslator

NewBlockTranslator returns the block translator for the given chain

func (*DiscovererDatabase) ReadAnnouncements 

func (d *DiscovererDatabase) ReadAnnouncements(ctx context.Context, peerIDs []string) (map[string][]byte, error)

ReadAnnouncements returns one serialized announcement (if available) for each of the peerIDs in the form of a map keyed by each announcement's corresponding peer ID.

func (*DiscovererDatabase) StoreAnnouncement 

func (d *DiscovererDatabase) StoreAnnouncement(ctx context.Context, peerID string, ann []byte) error

StoreAnnouncement has key-value-store semantics and stores a peerID (key) and an associated serialized announcement (value).
