Trait Implementations

impl<L: Layout> Builder for OrdValBuilder<L>

type Item = ((<<L as Layout>::Target as Update>::Key, <<L as Layout>::Target as Update>::Val), <<L as Layout>::Target as Update>::Time, <<L as Layout>::Target as Update>::Diff)

Input item type.

type Time = <<L as Layout>::Target as Update>::Time

Timestamp type.

type Output = OrdValBatch<L>

fn with_capacity(keys: usize, vals: usize, upds: usize) -> Self

Allocates an empty builder with capacity for the specified keys, values, and updates.

fn push(&mut self, ((key, val), time, diff): Self::Item)

Adds an element to the batch.

fn copy(&mut self, ((key, val), time, diff): &Self::Item)

Adds an element to the batch.

fn done( self, lower: Antichain<Self::Time>, upper: Antichain<Self::Time>, since: Antichain<Self::Time>, ) -> OrdValBatch<L>

Completes building and returns the batch.

fn new() -> Self

Allocates an empty builder.

fn extend<I: Iterator<Item = Self::Item>>(&mut self, iter: I)
