3/// Configuration for a aws_sdk_sts service client.
4///
5/// Service configuration allows for customization of endpoints, region, credentials providers,
6/// and retry configuration. Generally, it is constructed automatically for you from a shared
7/// configuration loaded by the `aws-config` crate. For example:
8///
9/// ```ignore
10/// // Load a shared config from the environment
11/// let shared_config = aws_config::from_env().load().await;
12/// // The client constructor automatically converts the shared config into the service config
13/// let client = Client::new(&shared_config);
14/// ```
15///
16/// The service config can also be constructed manually using its builder.
17///

1673/// [`RetryConfig`](crate::config::retry::RetryConfig) sets the number of retry attempts and the backoff between them. Retries are additionally bounded by a retry token bucket (a shared retry quota): [`TokenBucket`](crate::config::retry::TokenBucket) holds the tokens and [`RetryPartition`](crate::config::retry::RetryPartition) determines which clients and operations share one. To size the token bucket or give a workload its own, use [`Builder::retry_partition`](crate::config::Builder::retry_partition).
