Trait ProvideCredential 

pub trait ProvideCredential:
    Debug
    + Send
    + Sync
    + Unpin
    + 'static {
    type Credential: Send + Sync + Unpin + 'static;

    // Required method
    fn provide_credential(
        &self,
        ctx: &Context,
    ) -> impl Future<Output = Result<Option<Self::Credential>>> + MaybeSend;
}

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( &self, ctx: &Context, ) -> impl Future<Output = Result<Option<Self::Credential>>> + MaybeSend

Load signing credential from current env.
