Struct aws_config::default_provider::credentials::DefaultCredentialsChain

pub struct DefaultCredentialsChain(_);

Default AWS Credential Provider Chain

Resolution order:

1. Environment variables: EnvironmentVariableCredentialsProvider
2. Shared config (~/.aws/config, ~/.aws/credentials): SharedConfigCredentialsProvider

The outer provider is wrapped in a refreshing cache.

More providers are a work in progress.

Examples

Create a default chain with a custom region:

use aws_types::region::Region;
use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder()
    .region(Region::new("us-west-1"))
    .build();

Create a default chain with no overrides:

use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder().build();

Create a default chain that uses a different profile:

use aws_config::default_provider::credentials::DefaultCredentialsChain;
let credentials_provider = DefaultCredentialsChain::builder()
    .profile_name("otherprofile")
    .build();
