StateEvictHint

Enum StateEvictHint 

Source 
pub enum StateEvictHint {
    CanEvict(BTreeSet<StateKey>),
    CannotEvict(StateKey),
}

Variants§

§

CanEvict(BTreeSet<StateKey>)

Use a set instead of a single key to avoid state table iter or too many range delete. Shouldn’t be empty set.

§

CannotEvict(StateKey)

State keys from the specified key are still required, so must be kept in the state table.
