func NewBoltStore ¶

func NewBoltStore(ctx context.Context, l log.Logger, folder string, opts *bolt.Options) (chain.Store, error)

NewBoltStore returns a Store implementation using the boltdb storage engine.

Types ¶

type BoltStore ¶ added in v1.5.3

type BoltStore struct {
	sync.Mutex
	// contains filtered or unexported fields

func (b *BoltStore) Close(context.Context) error

func (*BoltStore) Cursor ¶ added in v1.5.3

func (b *BoltStore) Cursor(ctx context.Context, fn func(context.Context, chain.Cursor) error) error

func (*BoltStore) Del ¶ added in v1.5.3

func (b *BoltStore) Del(ctx context.Context, round uint64) error

func (*BoltStore) Get ¶ added in v1.5.3

func (b *BoltStore) Get(ctx context.Context, round uint64) (*chain.Beacon, error)

Get returns the beacon saved at this round

func (*BoltStore) Last ¶ added in v1.5.3

Put implements the Store interface. WARNING: It does NOT verify that this beacon is not already saved in the database or not and will overwrite it.
