            List returns all keys in the store.

            func (*FileStore) Read

            func (f *FileStore) Read(key string) ([]byte, error)

              Read reads the data from the file named key.

              func (*FileStore) Write

                	// Write writes data with key.
                	Write(key string, data []byte) error
                	// Read retrieves data with key
                	// Read must return ErrKeyNotFound if key is not found.
