Enum Supersede 

pub enum Supersede {
    Exact(TokenHash),
    CurrentIssuedBefore(DateTime<Utc>),
    Current,
}

Which token a Rotation replaces. Each variant is a condition evaluated atomically against the session’s current token; if it does not hold, nothing rotates.

Variants

Exact(TokenHash)

Only if this exact token is still current. Two concurrent requests with the same token both ask for this; exactly one wins.

CurrentIssuedBefore(DateTime<Utc>)

Only if the current token was issued strictly before this instant.

Current

Whatever token is current.
