Struct aws_http::auth::CredentialsStage

#[non_exhaustive]
pub struct CredentialsStage;

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

CredentialsStage implements AsyncMapRequest, and:

1. Retrieves a SharedCredentialsCache from the property bag.
2. Calls the credential cache’s provide_cached_credentials and awaits its result.
3. Places returned Credentials into the property bag to drive downstream signing middleware.

Implementations

impl CredentialsStage

pub fn new() -> Self
