Types ¶

type Migrator ¶

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

func New ¶

func New(retainedBlocks uint64, minAge time.Duration) *Migrator

New constructs a history pruner migrator. retainedBlocks is the number of blocks retained below the L1-confirmed head; the head itself is always retained on top. retainedBlocks == 0 keeps only the L1 head plus the reorg-safe window above it. minAge layers a wallclock floor on top: blocks whose on-chain timestamp is younger than minAge are also retained, mirroring the running pruner's --prune-min-age. Zero disables it.

func (*Migrator) Before ¶

func (m *Migrator) Before(state []byte) error

Before restores stager/restorer progress and the pinned cutoff from persisted intermediate state. A nil/empty state means a fresh run — the cutoff is computed on the first Migrate call. Once pinned, retainedBlocks and minAge config changes between runs are ignored until completion.

func (*Migrator) Migrate ¶

func (m *Migrator) Migrate(
	ctx context.Context,
	database db.KeyValueStore,
	network *networks.Network,
	logger log.StructuredLogger,
) ([]byte, error)
