fn new() -> Self

Allocates an empty builder.

fn with_capacity(cap: usize) -> Self

Allocates an empty builder with some capacity.

fn push(&mut self, (key, _, time, diff): (K, (), T, R))

Adds an element to the batch.

fn done(
    self,
    lower: Antichain<T>,
    upper: Antichain<T>,
    since: Antichain<T>
) -> OrdKeyBatch<K, T, R, O>

Completes building and returns the batch.

fn extend<I: Iterator<Item = (K, V, T, R)>>(&mut self, iter: I)

Adds an ordered sequence of elements to the batch.
