Auto-generated vision v1 clients

This package includes auto-generated clients for the vision v1 API.

Use the handwritten client (in the parent directory, cloud.google.com/go/vision) in preference to this.

This code is EXPERIMENTAL and subject to CHANGE AT ANY TIME.

Functions

func DefaultAuthScopes added in v0.8.0 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

func NewImageFromReader added in v0.8.0 

func NewImageFromReader(r io.Reader) (*pb.Image, error)

NewImageFromReader reads the bytes of an image from r.

func NewImageFromURI added in v0.8.0

Types

type AsyncBatchAnnotateFilesOperation added in v0.24.0 

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

AsyncBatchAnnotateFilesOperation manages a long-running operation from AsyncBatchAnnotateFiles.

func (*AsyncBatchAnnotateFilesOperation) Done added in v0.24.0 

func (op *AsyncBatchAnnotateFilesOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*AsyncBatchAnnotateFilesOperation) Metadata added in v0.24.0 

func (op *AsyncBatchAnnotateFilesOperation) Metadata() (*visionpb.OperationMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*AsyncBatchAnnotateFilesOperation) Name added in v0.24.0 

func (op *AsyncBatchAnnotateFilesOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*AsyncBatchAnnotateFilesOperation) Poll added in v0.24.0 

func (op *AsyncBatchAnnotateFilesOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*visionpb.AsyncBatchAnnotateFilesResponse, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*AsyncBatchAnnotateFilesOperation) Wait added in v0.24.0 

func (op *AsyncBatchAnnotateFilesOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*visionpb.AsyncBatchAnnotateFilesResponse, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.
