Enum Scope 

#[non_exhaustive]
pub enum Scope {
    Ephemeral,
    Conversation(String),
    Persistent {
        ttl: Duration,
    },
}

Lifetime scope of a Session’s token manifest.

Variant	Use case	export() allowed
Ephemeral	Single-pass sanitization, no restore needed	No
Conversation(id)	Multi-turn LLM sessions	Yes
Persistent { ttl: Duration }	Long-lived sessions across restarts	Yes

Persistent’s ttl is a std::time::Duration. SensitiveSnapshots exported from a persistent session carry the TTL; Session::import returns Error::BlobExpired { .. } once the deadline has elapsed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
