Types

type Backend

type Backend struct {
	// contains filtered or unexported fields
}

Level1Backend implements a level 1 drkey DB with sqlite.

func NewBackend

func NewBackend(path string) (*Backend, error)

NewLevel1Backend creates a database and prepares all statements.

func (*Backend) Close

func (b *Backend) Close() error

Close closes the database connection.

func (Backend) DeleteExpiredLevel1Keys

func (e Backend) DeleteExpiredLevel1Keys(ctx context.Context, cutoff time.Time) (int, error)

DeleteExpiredLevel1Keys removes all expired Level1 key, i.e. all the keys which expiration time is strictly smaller than the cutoff

func (Backend) GetLevel1Key

func (e Backend) GetLevel1Key(
	ctx context.Context,
	meta drkey.Level1Meta,
) (drkey.Level1Key, error)

GetLevel1Key takes metadata information for the Level1 key and a timestamp at which it should be valid and returns the corresponding Level1Key.

func (Backend) InsertLevel1Key

func (e Backend) InsertLevel1Key(ctx context.Context, key drkey.Level1Key) error

InsertLevel1Key inserts a Level1 key.

func (*Backend) SetMaxIdleConns

func (b *Backend) SetMaxIdleConns(maxIdleConns int)

SetMaxIdleConns sets the maximum number of idle connections.

func (*Backend) SetMaxOpenConns

func (b *Backend) SetMaxOpenConns(maxOpenConns int)

SetMaxOpenConns sets the maximum number of open connections.
