Trait differential_dataflow::trace::Builder

pub trait Builder<K, V, T, R, Output: Batch<K, V, T, R>> {
    fn new() -> Self;
    fn with_capacity(cap: usize) -> Self;
    fn push(&mut self, element: (K, V, T, R));

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

Functionality for building batches from ordered update sequences.

Required methods

fn new() -> Self

Allocates an empty builder.

fn with_capacity(cap: usize) -> Self

Allocates an empty builder with some capacity.

fn push(&mut self, element: (K, V, T, R))

Adds an element to the batch.

fn done(self, lower: &[T], upper: &[T], since: &[T]) -> Output

Completes building and returns the batch.
