# Google Cloud Client Libraries for Rust - Cloud Optimization API
Cloud Optimization API provides a portfolio of solvers to address common
optimization use cases starting with optimal route planning for vehicle
fleets.
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:
