BridgeEvent stores data for emitted events from the Bridge contract.

type EventType

type EventType int8

EventType is an enum for event types.

type Store

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

Store is the clickhouse store. It extends the base store for sqlite specific queries.

func OpenGormClickhouse

func OpenGormClickhouse(ctx context.Context, address string) (*Store, error)

OpenGormClickhouse opens a gorm connection to clickhouse.

func (Store) DB

func (s Store) DB() *gorm.DB

DB gets the underlying gorm db.

func (*Store) ReadBlockNumberByChainID

func (s *Store) ReadBlockNumberByChainID(ctx context.Context, eventType int8, chainID uint32) (*uint64, error)

ReadBlockNumberByChainID provides an easy-to-use interface to validate database data from a recent write event via chain id.

func (*Store) StoreEvent

func (s *Store) StoreEvent(ctx context.Context, bridgeEvent bridge.EventLog, swapEvent swap.EventLog, chainID uint32, tokenID *string) error

StoreEvent stores a generic event that has the proper fields set by `eventToBridgeEvent`.
