Specify User Agent string in AWS SDK for Rust

[trevorstr]

I'd like to override the User Agent string for my application in the AWS SDK. In the AWS CloudTrail logs, I need to be able to filter API calls coming from a specific application. The easiest way I can see to do this would be to specify a custom User Agent header, so I can filter on that field. How can I accomplish this with the AWS SDK for Rust?

Rather than wholesale override the User Agent header you can try giving the configuration an application name which will be added to the User Agent header.

e.g.

    let config = aws_config::defaults(BehaviorVersion::latest())
        .app_name(AppName::new("my-application").expect("valid app name"))
        // ... other settings
        .load()
        .await;

     let s3 = aws_sdk_s3::Client::new(&config);

This will add app/my-application to the User-Agent header used by the SDK.

See ConfigLoader.app_name.

Cool, that should work, thanks!
