type Input = CI

Input item type.

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

Timestamp type.

type Output = OrdKeyBatch<L>

Output batch type.

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, chunk: &mut Self::Input)

Adds a chunk of elements to the batch.

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

Completes building and returns the batch.

fn new() -> Self

Allocates an empty builder.
