Client is used to operate on blobs in a blobstore

func NewMetricClient

func NewMetricClient(client Client, metricsClient metrics.Client) Client

NewMetricClient creates a new instance of Client that emits metrics

func NewRetryableClient

func NewRetryableClient(client Client, policy backoff.RetryPolicy, isRetryable backoff.IsRetryable) Client

NewRetryableClient creates a new instance of Client with retry policy
