Override region on AWS SDK configuration (SdkConfig struct)

[trevorstr]

I have an AWS SdkConfig struct that I'm sharing via an Arc<T>. I need to override the region for specific AWS SDK requests.

However, the SdkConfig struct doesn't have any method defined on it to specify the region that should be used. It only has a .region() method that takes zero parameters. This returns the region, but doesn't allow me to specify the region.

➡️ Question: How do I specify a region on an SdkConfig struct?

This seems like something that should be extremely straightforward. Shouldn't I be able to call .region("us-west-2") on the SdkConfig?

The SdkConfig struct is essentially immutable after it is built. If you want to override the region on it after building it, you can use its to_builder() method to convert it back to a builder, set the region, and then build it again.

Thanks, that seems to work alright.

let new_sdk = aws_creds.clone().into_builder().region(aws_config::Region::new("us-west-1")).build();

I need to override the region for specific AWS SDK requests.

If you need to override a region just for a specific operation, you can also use config_override on that operation.
We have an example in the SDK example repository.
