Enum clepsydra::Entry

pub enum Entry<L: Lang> {
    Delayed(L::Expr, Vec<L::Val>, ReplicationTag),
    Settled(ExtVal<L>, ReplicationTag),
    Aborted,
}

An Entry is associated with each KeyVer (i.e. a Lang::Key at some GlobalTime) in the Store, and is either an unevaluated expression of type Entry::Delayed (at one of two possible ReplicationTag levels), or an Entry::Aborted tombstone (if replication fails), or an Entry::Settled value carrying a fully-evaluated ExtVal.

Variants

Delayed(L::Expr, Vec<L::Val>, ReplicationTag)

Settled(ExtVal<L>, ReplicationTag)

Aborted
