Configuring service clients in the Amazon SDK for Rust

To programmatically access Amazon Web Services services, the Amazon SDK for Rust uses a client struct for each Amazon Web Services service. For example, if your application needs to access Amazon EC2, your application creates an Amazon EC2 client struct to interface with that service. You then use the service client to make requests to that Amazon Web Services service.

To make a request to an Amazon Web Services service, you must first create a service client. For each Amazon Web Services service your code uses, it has its own crate and its own dedicated type for interacting with it. The client exposes one method for each API operation exposed by the service.

There are many alternative ways to configure SDK behavior, but ultimately everything has to do with the behavior of service clients. Any configuration has no effect until a service client that is created from them is used.

You must establish how your code authenticates with Amazon when you develop with Amazon Web Services services. You must also set the Amazon Web Services Region you want to use.

The Amazon SDKs and Tools Reference Guide also contains settings, features, and other foundational concepts common among many of the Amazon SDKs.
