Types

type State

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

State represents a management object that handles the internal logic of maintaining both hot and cold states in DB.

func New

func New(db db.NoHeadAccessDatabase) *State

New returns a new state management object.

func (*State) LoadBlocks

func (s *State) LoadBlocks(ctx context.Context, startSlot uint64, endSlot uint64, endBlockRoot [32]byte) ([]*ethpb.SignedBeaconBlock, error)

LoadBlocks loads the blocks between start slot and end slot by recursively fetching from end block root. The Blocks are returned in slot-descending order.

func (*State) ReplayBlocks

func (s *State) ReplayBlocks(ctx context.Context, state *state.BeaconState, signed []*ethpb.SignedBeaconBlock, targetSlot uint64) (*state.BeaconState, error)

ReplayBlocks replays the input blocks on the input state until the target slot is reached.
