Types

type BoltStore

type BoltStore struct {
	FileName string
}

BoltStore is a BoltDB implementation of the Store interface

func (*BoltStore) GetConnection

func (b *BoltStore) GetConnection() (*bolt.DB, error)

func (*BoltStore) List

func (b *BoltStore) List(offset uint64, limit uint64) (result []*Version, err error)

List lists all version starting at a given id

func (*BoltStore) Put

func (b *BoltStore) Put(version *Version) error

Put stores version in Bolt

func (*BoltStore) Retrieve

func (b *BoltStore) Retrieve(id uint64) (*Version, error)

Retrieve loads data from db by version ID

type Version

type Version struct {
	Id   uint64
	Date time.Time
	User string
	Log  string
	Data interface{}
}

Version is a structure for encapsulating a new version of configs with additional metadata

type VersionsStore

type VersionsStore interface {
	Put(version *Version) error
	List(offset uint64, limit uint64) ([]*Version, error)
	Retrieve(id uint64) (*Version, error)
}

VersionsStore is the interface for storing and listing configs versions

func NewStore

func NewStore(configDir string) VersionsStore

NewStore opens a new store
