pub struct CredentialsStage;
Expand description

Middleware stage that loads credentials from a CredentialsProvider and places them in the property bag of the request.

CredentialsStage implements AsyncMapRequest, and:

  1. Retrieves a CredentialsProvider from the property bag.
  2. Calls the credential provider’s provide_credentials and awaits its result.
  3. Places returned Credentials into the property bad to drive downstream signing middleware.
