Close the bolt database

func (*Db) Delete

func (bdb *Db) Delete(key []byte) (err error)

Delete deletes a key from database.

func (*Db) Get

func (bdb *Db) Get(key []byte) (hist *game.Hist, err error)

Get fetches a game history from the database.

func (*Db) Gets

func (bdb *Db) Gets(keys [][]byte) (hists []*game.Hist, err error)

Gets fetches multiple games from database.

func (*Db) Init

Init inits the battleline bucket if does not exist.

func (*Db) Key

func (bdb *Db) Key(hist *game.Hist) []byte

Key returns the key.

func (*Db) MaxFetchNo

func (bdb *Db) MaxFetchNo() int

MaxFetchNo returns the max. number of records fetched in search.

func (*Db) Put

func (bdb *Db) Put(hist *game.Hist) (err error)

Put adds a history of a game to the bucket.

func (*Db) Puts

func (bdb *Db) Puts(hists []*game.Hist) (err error)

Puts adds muliple histories to bucket.

func (*Db) ScannPrefix

func (bdb *Db) ScannPrefix(
	filterFunc func(hist *game.Hist) bool,
