+# Google Cloud Client Libraries for Rust - Gemini Enterprise for Customer Experience API
+
+<!-- Code generated by sidekick. DO NOT EDIT. -->
+
+**WARNING:** some RPCs have no corresponding Rust function to call them.
+Typically these are streaming RPCs. We expect adding these RPCs in a
+way that does not break the existing APIs or changes their behavior in a
+significant way. We do anticipate a number of new crate dependencies
+will be required. If you need these RPCs please open an issue in our
+GitHub repository.
+
+The client library types and functions are stable and not expected to change.
+Please note that Google Cloud services do change from time to time. The client
+libraries are designed to preserve backwards compatibility when the service
+changes in compatible ways. For example, adding RPCs, or fields to messages
+should not introduce breaking changes to the client libraries.
+
+## Quickstart
+
+The main types to work with this crate are the clients:
+
+- [AgentService]
+- [SessionService]
+- [ToolService]
+- [WidgetService]
+
+## Features
+
+- `default-rustls-provider`: enabled by default. Use the default rustls crypto
+  provider ([aws-lc-rs]) for TLS and authentication. Applications with specific
+  requirements for cryptography (such as exclusively using the [ring] crate)
+  should disable this default and call
+  `rustls::crypto::CryptoProvider::install_default()`.
+
+## More Information
+
