ProvideCredential is the trait used by signer to load the credential from the environment. ` Service may require different credential to sign the request, for example, AWS require access key and secret key, while Google Cloud Storage require token.

Required Associated Types

type Credential: Send + Sync + Unpin + 'static

Credential returned by this loader.

Typically, it will be a credential.

Required Methods

fn provide_credential<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<Option<Self::Credential>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load signing credential from current env.
