type Deleter ¶
Deleter wraps the database delete operation supported by both batches and regular databases.
type LDBDatabase ¶
type LDBDatabase struct {
// contains filtered or unexported fields
}
func NewLDBDatabase ¶
func NewLDBDatabase(file string) (*LDBDatabase, error)
NewLDBDatabase returns a LevelDB wrapped object.
func (*LDBDatabase) Close ¶
func (db *LDBDatabase) Close()
func (*LDBDatabase) Delete ¶
func (db *LDBDatabase) Delete(key []byte) error
Delete deletes the key from the queue and database
func (*LDBDatabase) Get ¶
func (db *LDBDatabase) Get(key []byte) ([]byte, error)
