Struct aws_sdk_rust::aws::common::credentials::ChainProvider

pub struct ChainProvider {
    // some fields omitted
}

Provides AWS credentials from multiple possible sources using a priority order.

The following sources are checked in order for credentials when calling credentials:

1. Environment variables: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
2. AWS credentials file. Usually located at ~/.aws/credentials.
3. IAM instance profile. Will only work if running on an EC2 instance with an instance profile/role.

If the sources are exhausted without finding credentials, an error is returned.
