Crate aws_config

Expand description

aws-config provides implementations of region and credential resolution.

These implementations can be used either via the default chain implementation from_env/ConfigLoader or ad-hoc individual credential and region providers.

ConfigLoader can combine different configuration sources into an AWS shared-config: SdkConfig. SdkConfig can be used configure an AWS service client.

Examples

Load default SDK configuration:

let config = aws_config::load_from_env().await;
let client = aws_sdk_dynamodb::Client::new(&config);

Load SDK configuration with a region override:

let region_provider = RegionProviderChain::default_provider().or_else("us-east-1");
let config = aws_config::from_env().region(region_provider).load().await;
let client = aws_sdk_dynamodb::Client::new(&config);

Override configuration after construction of SdkConfig:

let sdk_config = aws_config::load_from_env().await;
let custom_credentials_provider = custom_provider(&sdk_config);
let dynamo_config = aws_sdk_dynamodb::config::Builder::from(&sdk_config)
  .credentials_provider(custom_credentials_provider)
  .build();
let client = aws_sdk_dynamodb::Client::from_conf(dynamo_config);
