	logger logging.Logger, option ...option.ClientOption) (*Client, error)

NewStorageClient creates a Client

func (*Client) Buckets 

func (sc *Client) Buckets(projectID string) *storage.BucketIterator

Buckets returns a bucket iterator for all buckets within a project

func (*Client) Close 

func (sc *Client) Close() error

Close closes the Client.

Close need not be called at program exit.

func (*Client) CreateBucket 

func (sc *Client) CreateBucket(
	bucketName string, project string, attrs *storage.BucketAttrs) error

CreateBucket creates a GCS bucket

func (*Client) DeleteGcsPath 

func (sc *Client) DeleteGcsPath(gcsPath string) error

DeleteGcsPath deletes a GCS path, including files

func (*Client) DeleteObject 

func (sc *Client) DeleteObject(gcsPath string) error

DeleteObject deletes the object with the path `gcsPath`.

func (*Client) FindGcsFile 

func (sc *Client) FindGcsFile(gcsDirectoryPath string, fileExtension string) (*storage.ObjectHandle, error)

FindGcsFile finds a file in a GCS directory path for given file extension. File extension can be a file name as well. The lookup is done recursively.

func (*Client) FindGcsFileDepthLimited 

func (sc *Client) FindGcsFileDepthLimited(gcsDirectoryPath string, fileExtension string, lookupDepth int) (*storage.ObjectHandle, error)

FindGcsFileDepthLimited finds a file in a GCS directory path for given file extension up to lookupDepth deep. If lookup should be only for files directly in gcsDirectoryPath, lookupDepth should be set as 0. For recursive lookup with no limitations on depth, lookupDepth should be -1 File extension can be a file name as well.

func (*Client) GetBucket 

func (sc *Client) GetBucket(bucket string) *storage.BucketHandle

GetBucket returns a BucketHandle, which provides operations on the named bucket.

func (*Client) GetBucketAttrs 

func (sc *Client) GetBucketAttrs(bucket string) (*storage.BucketAttrs, error)
