# Code examples for Amazon Cognito Sync using AWS SDKs
<a name="service_code_examples_cognito-sync"></a>

The following code examples show how to use Amazon Cognito Sync with an AWS software development kit (SDK). 

*Actions* are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

For a complete list of AWS SDK developer guides and code examples, see [Using this service with an AWS SDK](sdk-general-information-section.md). This topic also includes information about getting started and details about previous SDK versions.

The following code examples demonstrate how to perform individual Amazon Cognito Sync actions with AWS SDKs. Each example includes a link to GitHub, where you can find instructions for setting up and running the code. 

 The following examples include only the most commonly used actions. For a complete list, see the [Amazon Cognito Sync API Reference](https://docs.aws.amazon.com/cognitosync/latest/APIReference/Welcome.html).

```

    let pools = response.identity_pool_usages();
    println!("Identity pools:");

    for pool in pools {
        println!(
            "  Identity pool ID:    {}",
            pool.identity_pool_id().unwrap_or_default()
        );
        println!(
            "  Data storage:        {}",
            pool.data_storage().unwrap_or_default()
        );

            pool.sync_sessions_count().unwrap_or_default()

            pool.last_modified_date().unwrap().to_chrono_utc()?

    println!("Next token: {}", response.next_token().unwrap_or_default());

    Ok(())
