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, val, time, diff): (K, V, T, R))

Adds an element to the batch.

fn done(self, lower: &[T], upper: &[T], since: &[T]) -> OrdValBatch<K, V, T, R>

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.
