Types

type Client

type Client[H types.Head[BLOCK_HASH], S types.Subscription, ID types.ID, BLOCK_HASH types.Hashable] interface {
	HeadByNumber(ctx context.Context, number *big.Int) (head H, err error)
	// ConfiguredChainID returns the chain ID that the node is configured to connect to
	ConfiguredChainID() (id ID)
	// SubscribeNewHead is the method in which the client receives new Head.
	// It can be implemented differently for each chain i.e websocket, polling, etc
	SubscribeNewHead(ctx context.Context, ch chan<- H) (S, error)
}

type Config

type Config interface {
	BlockEmissionIdleWarningThreshold() time.Duration
	FinalityDepth() uint32
}

type Head

type Head[BLOCK_HASH types.Hashable, CHAIN_ID types.ID] interface {
	types.Head[BLOCK_HASH]
	// ChainID returns the chain ID that the head is for
	ChainID() CHAIN_ID
	// Returns true if the head has a chain Id
	HasChainID() bool
	// IsValid returns true if the head is valid.
	IsValid() bool
}

type HeadTrackerConfig

type HeadTrackerConfig interface {
	HistoryDepth() uint32
	MaxBufferSize() uint32
	SamplingInterval() time.Duration
