Asynchronous Credentials Provider

Required Methods

fn provide_credentials<'a>(&'a self) -> ProvideCredentials<'a>

where Self: 'a,

Returns a future that provides credentials.

Provided Methods

fn fallback_on_interrupt(&self) -> Option<Credentials>

Returns fallback credentials.

This method should be used as a fallback plan, i.e., when a call to provide_credentials is interrupted and its future fails to complete.

The fallback credentials should be set aside and ready to be returned immediately. Therefore, the user should NOT go fetch new credentials within this method, which might cause a long-running operation.

Trait Implementations

impl AsRef<dyn ProvideCredentials> for SharedCredentialsProvider

fn as_ref(&self) -> &(dyn ProvideCredentials + 'static)

Converts this type into a shared reference of the (usually inferred) input type.

Implementations on Foreign Types

impl ProvideCredentials for Arc<dyn ProvideCredentials>

fn provide_credentials<'a>(&'a self) -> ProvideCredentials<'a>

where Arc<dyn ProvideCredentials>: 'a,
