Struct DefaultCredentialProvider 

pub struct DefaultCredentialProvider { /* private fields */ }

DefaultCredentialProvider is a loader that will try to load credential via default chains.

Resolution order:

1. Environment variables
2. Assume Role with OIDC

Implementations

impl DefaultCredentialProvider

pub fn builder() -> DefaultCredentialProviderBuilder

Create a builder to configure the default credential chain.

pub fn new() -> Self

Create a new DefaultCredentialProvider instance using the default chain.

pub fn with_chain(chain: ProvideCredentialChain<Credential>) -> Self

Create with a custom credential chain.

pub fn push_front( self, provider: impl ProvideCredential<Credential = Credential> + 'static, ) -> Self

Add a credential provider to the front of the default chain.

This allows adding a high-priority credential source that will be tried before all other providers in the default chain.

Example

use reqsign_aliyun_oss::{DefaultCredentialProvider, StaticCredentialProvider};

let provider = DefaultCredentialProvider::new()
    .push_front(StaticCredentialProvider::new("access_key_id", "access_key_secret"));
