Struct coord::coord::arrangement_state::ArrangementFrontiers [−][src]
Expand description
A map from global identifiers to arrangement frontier state.
Fields
index: HashMap<GlobalId, Frontiers<T>>
Implementations
pub fn intersection(
&self,
ids: impl IntoIterator<Item = GlobalId>
) -> Vec<GlobalId>ⓘ
The upper frontier of a maintained index, if it exists.
The since frontier of a maintained index, if it exists.
pub fn greatest_open_upper<I>(&self, identifiers: I) -> Antichain<T> where
I: IntoIterator<Item = GlobalId>,
T: Lattice,
pub fn greatest_open_upper<I>(&self, identifiers: I) -> Antichain<T> where
I: IntoIterator<Item = GlobalId>,
T: Lattice,
Reports the greatest frontier less than all identified upper
frontiers.
pub fn least_valid_since<I>(&self, identifiers: I) -> Antichain<T> where
I: IntoIterator<Item = GlobalId>,
T: Lattice,
pub fn least_valid_since<I>(&self, identifiers: I) -> Antichain<T> where
I: IntoIterator<Item = GlobalId>,
T: Lattice,
Reports the minimal frontier greater than all identified since
frontiers.
