Types

type BlockProcessedData

type BlockProcessedData struct {
	// Slot is the slot of the processed block.
	Slot uint64
	// BlockRoot of the processed block.
	BlockRoot [32]byte
	// Verified is true if the block's BLS contents have been verified.
	Verified bool
}

BlockProcessedData is the data sent with BlockProcessed events.

type ChainStartedData

type ChainStartedData struct {
	// StartTime is the time at which the chain started.
	StartTime time.Time
}

ChainStartedData is the data sent with ChainStarted events.

type InitializedData

type InitializedData struct {
	// StartTime is the time at which the chain started.
	StartTime time.Time
	// GenesisValidatorsRoot represents state.validators.HashTreeRoot().
	GenesisValidatorsRoot []byte
}

InitializedData is the data sent with Initialized events.

type Notifier interface {
	StateFeed() *event.Feed
}

Notifier interface defines the methods of the service that provides state updates to consumers.

type ReorgData added in v1.0.0

	// NewSlot is the slot of new state after the reorg.
	NewSlot uint64
	// OldSlot is the slot of the head state before the reorg.
	OldSlot uint64
}

ReorgData is the data alongside a reorg event.

type SyncedData added in v1.0.0
