Enum CredentialType 

pub enum CredentialType {
    Impersonated,
    Downscoped,
    Hmac,
}

Which mechanism a role mints. The three differ in what they can be narrowed to and — more importantly — whether they can be revoked.

Variants

Impersonated

A plain impersonated token. Inherits every permission of the target service account, so prefer downscoped.

Downscoped

Impersonation followed by a Credential Access Boundary exchange, narrowing to one bucket and optionally one prefix.

Hmac

An S3-interoperability HMAC key. The only revocable credential here.
