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

pub struct ChainProvider { /* 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. Parameters option. This is set in your code however you wish to set it. For example, you could read from your own config file and set them or however.
2. Environment variables: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
3. AWS credentials file. Usually located at ~/.aws/credentials.
4. 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. NB: If the chain makes it to the IAM provider then TCP timeout may cause a wait.
