type Input = CI

Input item type.

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

Timestamp type.

type Output = OrdValBatch<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, description: Description<Self::Time>) -> OrdValBatch<L>

Completes building and returns the batch.

fn seal( chain: &mut Vec<Self::Input>, description: Description<Self::Time>, ) -> Self::Output

Builds a batch from a chain of updates corresponding to the indicated lower and upper bounds.

fn new() -> Self

Allocates an empty builder.
