Types ¶

type BoltStore ¶

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

BoltStore implements the Store interface using the kv storage boltdb (native golang implementation). Internally, Beacons are stored as JSON-encoded in the db file.

func (*BoltStore) Close ¶

func (b *BoltStore) Close() error

func (*BoltStore) Cursor ¶

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

func (*BoltStore) Del ¶

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

func (*BoltStore) Get ¶

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

Get returns the beacon saved at this round

func (*BoltStore) Last ¶

func (b *BoltStore) Last(ctx context.Context) (*common.Beacon, error)

Last returns the last beacon signature saved into the db

func (*BoltStore) Len ¶

func (b *BoltStore) Len(ctx context.Context) (int, error)

Len performs a big scan over the bucket and is _very_ slow - use sparingly!

func (*BoltStore) Put ¶

func (b *BoltStore) Put(ctx context.Context, beacon *common.Beacon) error

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.

func (*BoltStore) SaveTo ¶

func (b *BoltStore) SaveTo(ctx context.Context, w io.Writer) error

SaveTo saves the bolt database to an alternate file.
