Struct DefaultTokenChain

pub struct DefaultTokenChain { /* private fields */ }

Default access token provider chain

Currently, the default chain only examines the shared config (~/.aws/config) file and the SSO token cache to resolve an access token.

The AWS CLI can be used to retrieve the initial access token into the SSO token cache. Once it’s there, the SDK can refresh automatically long as the it remains refreshable (it will eventually expire).

Examples

Create a default chain with a custom region:

use aws_types::region::Region;
use aws_config::default_provider::token::DefaultTokenChain;
let token_provider = DefaultTokenChain::builder()
    .region(Region::new("us-west-1"))
    .build();

Create a default chain with no overrides:

use aws_config::default_provider::token::DefaultTokenChain;
let token_provider = DefaultTokenChain::builder().build();

Create a default chain that uses a different profile:

use aws_config::default_provider::token::DefaultTokenChain;
let token_provider = DefaultTokenChain::builder()
    .profile_name("otherprofile")
    .build();
