Enum MetadataPolicy 

pub enum MetadataPolicy {
    Allow,
    Forbid,
}

Whether credential discovery may fall through to the metadata server.

Variants

Allow

After user credentials, use the instance’s own identity (Cloud Run, GCE, GKE). The historical behaviour.

Forbid

Never contact the metadata server: without user credentials, discovery is Error::NoCredentials.
