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.
