Package documentai is an auto-generated package for the Cloud Document AI API.
Service to parse structured information from unstructured or semi-structured documents using state-of-the-art Google AI such as natural language, computer vision, translation, and AutoML.
NOTE : This package is in beta . It is not stable , and may be subject to changes .
Use of Context
The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.
For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go .
Functions

}
EnableProcessorOperation manages a long-running operation from EnableProcessor.
func (*EnableProcessorOperation) Done
func
(
op
*
EnableProcessorOperation
)
Done
()
bool
Done reports whether the long-running operation has completed.
func (*EnableProcessorOperation) Metadata
func
(
op
*
EnableProcessorOperation
)
Metadata
()
(
*
documentaipb
.
EnableProcessorMetadata
,
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 (*EnableProcessorOperation) Name
func
(
op
*
EnableProcessorOperation
)
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 (*EnableProcessorOperation) Poll
func

ctx
context
.
Context

CallOption
)
(
*
documentaipb
.
EnableProcessorResponse
,
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 (*EnableProcessorOperation) Wait

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.
See documentation of Poll for error-handling information.

// InternalFetch is for use by the Google Cloud Libraries only.
// It is not part of the stable interface of this package.
