Struct Replay 

pub struct Replay {
    seen: Mutex<SpentKeys>,
    kept: Option<SpentStore>,
}

Proofs already spent, each until its own expiry.

Swept on every spend rather than on a schedule: a create is rare enough that walking the window costs nothing, and the window is then never holding an entry it has stopped needing.

A deployment with a data directory keeps the window there too, so the proof a caller spent a second before a restart is still spent after it.

Fields

seen: Mutex<SpentKeys>

kept: Option<SpentStore>

Implementations

impl Replay

pub fn kept_in(store: SpentStore) -> Result<Self, SideStoreError>

A window kept in store, holding what it already had.

Errors

SideStoreError for a kept file that is there and cannot be read. It stops the boot: see didbot_pds::side_store.

pub fn spend( &self, key: String, until: OffsetDateTime, now: OffsetDateTime, ) -> Result<(), NotSpent>

Spends key until until.

Trait Implementations
