Types

type Store

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

Store is an in-memory key-value store. Its zero value is ready to use.

func (*Store) Create

func (s *Store) Create(_ context.Context, name string, value []byte) error

Create adds the given key to the store if and only if no entry for the given name exists. If an entry already exists it returns kes.ErrKeyExists.

func (*Store) Delete

func (s *Store) Delete(_ context.Context, name string) error

Delete removes the key with the given value, if it exists.

func (*Store) Get

func (s *Store) Get(_ context.Context, name string) ([]byte, error)

Get returns the key associated with the given name. If no entry for this name exists it returns kes.ErrKeyNotFound.

func (*Store) List

func (s *Store) List(ctx context.Context) (kms.Iter, error)

List returns a new iterator over the metadata of all stored keys.

func (*Store) Status

func (s *Store) Status(_ context.Context) (kms.State, error)

Status returns the state of the in-memory key store which is always healthy.
