Types

type Storage

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

Storage is a schematic storage in-memory cache.

func NewCache

func NewCache(underlying storage.Storage) *Storage

NewCache returns a new cache storage.

func (*Storage) Collect

func (s *Storage) Collect(ch chan<- prometheus.Metric)

Collect implements prom.Collector interface.

func (*Storage) Describe

func (s *Storage) Describe(ch chan<- *prometheus.Desc)

Describe implements prom.Collector interface.

func (*Storage) Get

func (s *Storage) Get(ctx context.Context, id string) ([]byte, error)

Get returns the schematic.

func (*Storage) Head

func (s *Storage) Head(ctx context.Context, id string) error

Head checks if the schematic exists.

func (*Storage) Put

func (s *Storage) Put(ctx context.Context, id string, data []byte) error

Put stores the schematic.
